Lily Allen Changes Her Name, Starts Work on Third Album

Lily Allen clutches her leopard print purse as she waits for the Issa Spring/Summer 2011 fashion show to begin at Somerset House during London Fashion week Sept.21.

Lily Allen's in-the-works third album will not be released under the name Lily Allen -- instead, the U.K. pop singer has officially changed her professional name to Lily Rose Cooper.

The announcement comes one year after the 27-year-old singer married Sam Cooper in a Gloucestershire, England ceremony. Last November, Cooper gave birth to a baby girl in England.

Meanwhile, the singer's follow-up to 2009's "It's Not Me, It's You" is officially in motion: a press release confirms that Cooper is recording new music written "over the past few months." In June, the singer posted on Twitter, ""You will be pleased to know that I am currently in the fucking studio with @GregKurstin," a producer who was integral to her "It's Not Me, It's You" work.

"It's great to work at my own pace, with no commitments other than to make music," Cooper said in a statement on Thursday (Aug. 2). "I'm excited to be heading back into the studio."

"It's Not Me, It's You" followed the singer's breakout 2006 debut "Alright, Still," which featured the singles "LDN" and "Smile." "5 O'Clock," a T-Pain single featuring Cooper and Wiz Khalifa, cracked the Top 10 of the Hot 100 late last year.
