Her new baby girl must be rubbing off on her!
Less than a month after giving birth to baby #2, Lily Allen's already bounced back and looking great!
The new mom flaunted her post-baby bod at the BAFTAs WilliamVintage dinner in London on Friday night in a hot pink, brocade gown that accentuated her shrinking waist and teal heels.
Lily's hair was a little on the messy side, but with a one month and a 14 month old at home, we'll cut her some slack.
Welcome back, girl!

Lily Allen just gave birth to her baby girl Marnie Rose Cooper last week, but despite the fact that she's sooooo happy with her new infant, she's upset at how the National Health Service has been treating her postnatal care.
On Monday, the British pop singer took to her Twitter to tell off the NHS, she wrote:

Congrats, Lily Allen!
The Who'd Have Known singer gave birth to her second child with hubby Sam Cooper late Tuesday night, and it's… a girl!
Aw! A kid sister for little Ethel!
The Brit songstress couldn't have been happier with the due date- her new daughter shares a birthday with music legends David Bowie and Elvis Presley!
Talk about good company! Maybe we'll have another pop icon on our hands? Well, in Lily's arms for now!
Welcome to the world, Marnie Rose Cooper!

Lily Allen is one musical mom!
Music is such a big part of the singer's life, she even has to have just the right music playing while giving birth to her forthcoming baby!
So hubby Sam Cooper is being incredibly sweet and making her a delivery mix of…
Um… death metal? Lily tweeted:

She looks like she’s ready to pop!
A very pregnant Lily Allen attended the British Fashion Awards tonight in London.
The Smile singer donned a midnight blue pleated gown that waterfalled over her very pregnant belly beautifully.
Lily's due to give birth to her second child next month, so needless to say we're quite impressed that she made an appearance, and an elegant one at that.
Well done, Mrs. Cooper!

And it's even got that signature Lily Allen — erm, we mean Lily Rose Cooper — pep!
Pink has been a wordy vixen recently, daily debuting new lyric videos featuring tracks from her upcoming album The Truth About Love, which gets unleashed Sept 18th!
Today we've already learned the words to riveting, riotous jam Are We All We Are?, and yesterday we heard a delightful duet between Pink and FUN. frontman Nate Ruess…
And now we're getting intimate with sassy tune True Love, with guest vocals from Lily Allen Rose Cooper (above)!
Lily has been mostly absent from the music scene after announcing her retirement almost three years ago, but Lily recently revealed she is BACK in the studio and working hard on her third album!
It's so nice to hear your cheeky charm again Lily! We need more 'f*ck you very much' anthems in our life!
And what a delectable platter of yummy samplings!
Pop-punker Pink is thisclose to shocking our brainz with the electric force of upcoming album The Truth About love, but before she frazzles our senses in full, we get a little teaser in the form of a full album sampling (above)!
The preview does NOT include the already smash single Blow Me (One Last Kiss) or a tune called Slut Like You, but it does feature a snippet from each of the other 11 songs.
We are already digging this record's diverse musical stylings and ADORE the duet with FUN.'s Nate Ruess on Give Me A Reason!
Unfortunatly, we don't hear the guest vocals of Lily Allen Rose Cooper OR Eminem, so we'll just have to wait with baited breath for The Truth About Love's complete edition, which is duet out September 17th!
Check out the album's FULL track list …AFTER THE JUMP!!!
