Taylor Swift owned the Billboard Music Awards [4] in Las Vegas on Sunday by taking home eight awards, and, as it turns out, she also owned the afterparty. Taylor's brother, Austin, who graduated from Notre Dame last weekend, shared a series of photo booth snaps from Taylor and Ed Sheeran's star-studded party. In the photos, Taylor is seen cozying up to her current squeeze, Calvin Harris, while Ed, Austin, and the boys of One Direction (sans her ex-boyfriend Harry Styles) strike hilarious poses for the camera. They are also all sporting fun props, including crowns, swords, gold chains, a wolverine claw, and a tiger mask. In the middle photo, Taylor and Calvin are seen engaging in a sweet eskimo kiss while rubbing their noses together. One Direction's rep told the UK's The Sun that Harry didn't stay in Vegas [5] after the show, so he opted out of all celebrations. See the funny party moments above, then see Taylor and Calvin's PDA from earlier in the night [6].
