Lily Allen's marriage bliss
The singer credits her husband for calming her down
Lily has opened up about her life and marriage to builder Sam Cooper, saying that it's thanks to him that she's happier with herself and more centred about her life.
Allen admitted that before meeting Sam she had quite a wild life and drank too much.
"I suppose I was doing all that because I wanted acceptance".
The Lucy In Disguise shop owner also said that she had her luggage personalised with the initials Lily Rose Cooper as soon as Sam popped the question and immediately practised her new signature.
"He was really freaked out when he saw it" she admitted.
The star headed straight from the jungle to panto...but clearly hadn't had time to learn her lines!
