Sripaada, 34, shared a post on Twitter to narrate the alleged incident.
"I'd like to remain anonymous. A few years back when I was in Mumbai, I was looking for my friend in the hotel we were staying in. I bumped into a very famous Sri Lankan cricketer during the IPL season who said my friend was in his room," the famous singer's post read.
"I go in and she's not. He then pushed me in the bed and proceeded to climb onto my face. Mind you I'm tall and about same body weight & I couldn't fight him back. I closed my eyes and mouth but he used my face. Then the hotel staff knocked on the door to replenish the bar which he went to open the door. I quickly ran into the washroom, washed my face and left as soon as the hotel staff left. I was humiliated. I knew people would say that you knowingly went to his room, he's famous, you wanted it or worse you deserve it," the post further read.

However, Sripaada didn't mention her friend's name, who too, did not name any cricketer in her post.
Significantly, Malinga is one of Sri Lanka's greatest bowlers with 306 ODI wickets and 90 T20I wickets.
Earlier on Wednesday, an Indian flight attendant had had accused Sri Lanka's World Cup-winning captain Arjuna Ranatunga of sexually harassing her.
It was the Mumbai bowlers, who came all guns blazing on a slow wicket, to wrap up the home side, who were chasing a modest 156-run target, on a paltry 109 runs. Lasith Malinga starred for the visitors with figures of 4/37, while Krunal Pandya and Hardik Pandya bagged couple of wickets each.
Chennai opener Murli Vijay was the only one to show some resistance as he managed to contribute a 35-ball 38.
Mumbai had also defeated Chennai by 37 runs in their last encounter earlier this season in Mumbai.
Chasing the target, Chennai were off to a worst-possible start as Malinga dismissed opener Shane Watson (8) before Hardik Pandya struck to send back Suresh Raina (2), reducing the yellow brigade to 22/2 in 3.1 overs.
Vijay tried his best to repair the major damages but lacked support from the other end as incoming batsman Ambati Rayudu also departed without opening his account. Krunal accounted for the wicket of the Chennai stumper.
Chennai's middle-order also fell like a pack of cards as they lost Kedar Jadhav (6) and Dhruv Shorey (5) cheaply. Things turned ugly for the hosts when Bumrah picked Vijay in the 12th over, leaving Chennai reeling at 66/6. Suryakumar Yadav took a stunning catch of Vijay at backward point off a Bumrah delivery.
Dwayne Bravo (20 off 17) and Mitchell Santner (22 off 20) were involved in a short 33-run partnership for the seventh wicket and kept Chennai's slim hope of winning alive. However, Malinga broke the partnership as the Sri Lankan pacer's slower delivery took a leading edge off Bravo's bat and the pacer moved a couple of steps backwards to take an easy catch.
The Mumbai bowlers then rattled the lower middle-order with ease as Deepak Chahar (0), Harbhajan Singh (1) also failed to bring any relief. Malinga put the final nail in the coffin after picking Santner in the 18th over to set up a comfortable victory for Mumbai.
Earlier, some disciplined bowling by Chennai restricted Mumbai to a modest 155/4 as Rohit Sharma contributed a 48-ball 67.
Rohit and Evin Lewis (32 off 30) were involved in a 75-run partnership for the second wicket and at one stage it looked as if the visitors will amass a massive total. However, after the fall of Lewis, the Chennai bowlers bowled economically and picked up wickets at regular intervals to deny Mumbai a big total.
For Chennai, Santner was the pick of the bowlers as he impressed with figures of 2/13 from his four overs, while Deepak -- the only Chennai bowler to leak runs -- and Tahir picked a wicket each.
Deepak conceded 46 runs from his four overs.
Put into bat, Deepak came up with an early breakthrough as he packed back an in-form Quinton de Kock (15) with Mumbai at 24 runs in 2.4 overs. While trying to go for the maximum, de Kock misread Deepak's slower delivery and a top-edge off his bat went up in the air and Rayudu took the catch with ease.
Lewis and Rohit then tried to repair the damage and took their side past the 50-run mark in 6.5 overs. They then steadily propelled Mumbai near the three-digit mark before Santner dismissed Lewis, with Mumbai scorecard reading 99/2.
Tahir further jolted the visitors as he sent back incoming batsman Krunal (1) cheaply, reducing Mumbai to 101/3.
After the addition of 21 runs in the visitor's score, Santner struck again to pick up the crucial wicket of a well-settled Rohit Sharma in the 17th over. Rohit's knock contained six boundaries and three hits into the stands.
Hardik Pandya (23 unbeaten off 18) and Keiron Pollard (13 unbeaten off 12) then added 33 runs in the remaining 22 balls as Mumbai reached a fighting total.
Brief scores
Mumbai Indians -- 155/4 (Rohit Sharma 67, Evin Lewis 32; Mitchell Santner 2/13) -- beat Chennai Super Kings -- 109 all out in 17.4 overs (Murli Vijay 38, Mitchell Santner 22; Lasith Malinga 4/37) -- by 46 runs.
Electing to bat, Sri Lanka managed a modest 232 for nine, riding on an unbeaten 115-ball 85 by Mathews.
The 1996 champions then returned to dismiss England for 212 in 47 overs to register only their second win in this World Cup.
Malinga (4/43) emerged as the star for Sri Lanka as he dismissed the top three -- James Vince (14), Jonny Bairstow (0) and Joe Root (57) and also accounted for Jos Buttler (10).
Off-spinner Dhananjaya de Silva (3/32) then moped up the tail with a quick three-wicket burst.
After Root's 89-ball fifty, Ben Stokes kept England in the hunt with a 89-ball 82 but he ran out of partners.
The win took Sri Lanka to fifth spot with six points from six matches, while England remained in third spot with eight points from six games.
Earlier, Mathews added 71 and 57 runs with Kusal Mendis (46) and Dhananjaya de Silva (29) for the fourth and sixth wickets, respectively, as Sri Lanka recovered from three for 2.
Playing his first World Cup game, Avishka Fernando, too, contributed with a 39-ball 49.
Chasing the total, England could not recover from the twin strike by Malinga and could score only 38 for two in the powerplay.
Root and Eoin Morgan (21) added 47 runs for the third wicket before Isuru Udana (2/41) produced a stunning caught-and-bowled effort to remove the skipper as England slipped to 73 for 3 in 18.4 overs.
Root completed his fifty off 78 balls and soon new man Stokes brought up the team hundred with a boundary off Pradeep.
Malinga then brought Sri Lanka back in the match when he had Root caught behind off a ball drifting down the leg side.
De Silva then had Moeen Ali holed out to long-off, while Chris Woakes' thin edge was caught by the keeper and another edge sent Adil Rashid back to the hut as England slipped to 178 for 8.
Earlier, Sri Lanka lost Dimuth Karunaratne (1) and Kusal Perera (2) in three balls to be reduced to three for 2.
Fernando then blasted six fours and two sixes, sharing some valuable runs with Mendis. But an upper cut gone wrong saw Sri Lanka lose Fernando and slip to 62 for three.
Leg-spinner Rashid struck twice on successive balls, removing Kusal Mendis and new man Jeevan Mendis (0), as Sri Lanka slumped to 133 for five in the 30th over.
Mathews and Dhananjaya then took the team close to the 200-mark.
Once Dhananjaya was removed by Archer in the 44th over, it was a lonely battle for Mathews.
Sri Lanka skipper Dimuth Karunaratne had on Monday said that Malinga has decided to call it a day from the 50-over format after the first ODI of the three-match series against Bangladesh.
Karunaratne said the 36-year-old former captain would only take part in the first match to be played on July 26.
"Friday will be the last day you will see me playing an ODI match," Malinga said in a video message on his Facebook page.
"If you can, please come for the match."
Malinga remained hopeful of representing Sri Lanka in the T20 World Cup next year.
"I hope to be able to take Sri Lanka to the next T20 World Cup," he said.
"I hope I will have an opportunity to play in that tournament, but if there are better players than me, I don't mind being left out," he said.
Malinga was initially named in the 22-man Sri Lanka squad for the series. The matches will be played on July 26, July 28 and July 31 at the R. Premadasa Stadium.
With 335 wickets in 225 ODIs, Malinga is Sri Lanka's third highest wicket-taker in ODI cricket after Muttiah Muralitharan (523) and Chaminda Vaas (399).
