Fashion maven Stella McCartney celebrated her 40th birthday with a rock 'n' roll gathering in London.
Among those toasting her health were Stella's newlywed pal Kate Moss, new parents Kate Hudson and her musician fiancé Matt Bellamy.
Meanwhile, good friend Gwyneth Paltrow added some Hollywood glamour.
U2's Bono and his wife Ali Hewson were also at the bash – held at Asprey House – as was fellow designer Tom Ford, actress Jaime Winstone and her ex Alfie Allen.
Guest of honour was, of course, Stella's father, Beatles legend Paul McCartney who rolled up with his fianceé Nancy Shevell.
The birthday girl, escorted to her party by husband Alasdhair Willis, was on sparkling form in an elegant blue dress, her hair tied up in a simple chignon.
Following the main event, guests were seen heading for an afterparty at Soho's Groucho Club.
They had all been given a pair of mugs to commemorate the occasion, each one featuring a photo of Stella as a child.
