She only gave birth to her second daughter, Marnie, in January, but Lily Allen was looking on top form as she arrived to see Millie Mackintosh marry Professor Green on Tuesday.
The singer attended the rapper and his gal's nuptials at Babington House in Frome, Somerset, with her hubby Sam Cooper.
She wore a gorgeous vintage-looking monochrome maxi dress with a check board top and a keyhole cutout at the bust.
She paired her dress with towering black platforms, a black Chanel handbag, and a pair of Ray Bans.
Lily was, however, spotted not-so-stylishly sneaking off for a cheeky ciggie before the ceremony. Slapped wrists, Lil.
Lily has a love of fashion, famously opening a vintage clothes store, Lucy In Disguise, on a TV documentary called Riches To Rags.
Wonder if she dipped into the collection for Millie's wedding? See pics of the nuptials here, and check out more Lily fashion moments below:
