London's most fashion-savvy shoppers know Christmas has well and truly arrived when the lights go on at Stella McCartney's Bruton Street boutique.
This year a hilarious time was had by all as The Fast Show's cult comedy duo Paul Whitehouse and Mark Williams had been invited to do the honours. And the gags were obviously coming thick and fast as Stella, who is heavily pregnant with her third child, was so creased up with laughter at one point she had to wipe away the tears.
Also having a blast was the designer's publisher husband, Alasdhair Willis, and her 30-year-old brother, musician and sculptor James. Sir Paul's son is even more discreet about his personal life than 36-year-old Stella, but seemed happy enough stepping into the limelight on this occasion in support of his big sister.
Among the A-list crowd joining the McCartneys were supermodel Linda Evangelista, bundled up against the cold and wearing a beanie hat, singer Louise Redknapp, showing where her fashion loyalties lie by toting one of Stella's cream studded clutches, and M&S muse Twiggy.
