The hitmaker said that her two sons Sean Preston, five, and Jayden James, four, from ex-husband Kevin Federeline, are her life``s priority now, reported Huffington Post online.
But right now, Spears is busy promoting her latest album ``Femme Fatale``, which she says is her best work till date.
"There are songs on this album that don``t sound like anything else and are completely revolutionary, but I also believe that this album expresses where I am today as a woman and is an evolution of who I am," said the singer who posed for famed photographer Mario Testino to promote the album.
The pictures reveal a glamorous and glowing side to the singer, who is dressed in designer creations for the shoot.
