London's DSTRKT club was the spot for Jay-Z and Kanye West's star-studded Watch the Throne afterparty last night. The rappers performed at the O2 Arena before meeting up with their famous friends to celebrate. Gwyneth Paltrow and husband Chris Martin came out for the bash, as did their pal Stella McCartney. Gwyneth and Chris's kids, Apple and Moses, got in on the fun earlier when they watched the concert with their mom. Rihanna also stepped out to party during an especially exciting weekend since her Battleship hit theaters on Friday. Kanye's girlfriend Kim Kardashian was on hand, along with her brother Rob, who had his girlfriend and Jay-Z protégé, Rita Ora, by his side. It was the second night out for the foursome, after they shared a double date at Zuma last week. Jay-Z and Kanye have three more shows in the UK before heading to Manchester.
