Call her the artist formerly known as Lily Allen.
The 27-year-old British singer says she is changing her stage name to reflect her marriage to Sam Cooper - and she's working on new material.
A statement from publicist Ambrosia Healey said the singer would now be known as Lily Rose Cooper, the name she already uses on her Twitter account.
She and Sam Cooper married last year, and the pair have a daughter.
Healey said the singer had booked time at a studio in Britain work on new material.
Cooper, whose hits include Smile and The Fear, said in the statement that she was "excited to be heading back into the studio".
