Lily Allen (now Cooper) gave birth to a baby girl early on Friday evening.
Lily had announced her pregnancy at her gorgeous Cotswolds wedding to Sam Cooper back in June, wearing a stunning lace wedding gown which revealed her burgeoning bump.
Keeping a low profile during the pregnancy, Lily spoke to her fans on Twitter, revealing earlier in the month that she'd been suffering from false labour pains.
On the Friday of the birth, Lily tweeted again to her fans: "Totes amaze" - we wonder if she knew what was coming!
Her Twitter page has been flooded with congratulations from her celeb friends and fans, with her close pal Seb Chew tweeting: "sending out love to lily, sam and mini cooper….. YES"
Congrats from all of us at InStyle to Lily, Sam and the little one!
