Lily Allen will stop drinking and smoking for the health of her unborn baby.

The 22-year-old "Smile" singer - who announced yesterday she is expecting her first child with her boyfriend, Chemical Brothers star Ed Simons - is reportedly determined to kick her heavy smoking habit.

Jamie Lynn Spears is not the only singer celebrating impending motherhood.

British singer Lily Allen is reportedly expecting her first child with her boyfriend of four months, Ed Simons.

Singer Lily Allen admits typical girl envy behavior. The then size 12 English artist had criticized her peers for doing sexy photo shoots, which she said she did all out of envy.

Allen had earlier called Girls Aloud singer Cheryl Tweedy for a "stupid bitch" for "taking her clothes off." But after losing almost 21 pounds down to size 8 in just six weeks, the Smile singer is now singing a different tune. She has posed for the latest issued of men's magazine, GQ in scantily clad attire.
