Lily Allen's Wee Baby Bump

Lily Allen shows off her new reason to smile–pregnancy!

The 22-year-old British singer was seen clearing out her car before greeting her father Keith Allen with a big hug in London on Thursday.

“I should also give up smoking,” she said last month, “but haven’t quite managed that yet.” Hope she’s managed to now!

Lily and boyfriend Ed Simons (one-half of the Chemical Brothers) are expecting their first child together mid-2008.
