Lily Allen's friends apparently worry she's been sucked back into a world she tried to get out of.
The British star burst on to the music scene in 2006 with debut single Smile, and was known for her love of partying.
She shunned the limelight and wild lifestyle when she met her now-husband Sam Cooper, and the couple and their two daughters Marnie and Ethel lived a quieter life.
But earlier this year Lily made a return to music with third studio album Sheezus.
"It's like, as soon as she had her new album out, she jumped into a Tardis and went back to Lily Allen 2005. She seemed to be keen to prove she could be a success again and could get the whole pop star mommy thing totally right," a source revealed to British magazine Grazia.
"But there are some who think she has succumbed to all the pressures that forced her to retreat from the spotlight last time. She's rumoured to have lost three stone on a self-proclaimed diet of crisps, she is prolific on Twitter and reacts to any negative comments. It feels as if she's allowing herself to get sucked right back into that world."
Since her return to music, Lily has enjoyed touring with Miley Cyrus in America.
Her new album received mix responses though, which is thought to have upset the 29-year-old.
"The crazy thing is it was such a battle for her to have kids and get out of the celebrity world. She was so happy when she married Sam, and she kept saying that all she ever wanted was a normal life in the country with and their kids," the insider added.© Cover Media
