Oh, baby, baby, Britney Spears just had an epic reunion with Kim Kardashian - and her sister Khloé Kardashian came along for the ride. "Calabasas Nights," Kim, 45, wrote via her Instagram Story on Friday, November 14, sharing a selfie with Khloé, 41, Spears, 43, and the "Circus" singer's manager, Cade Hudson. In the pic, the group lounged on a bed and made silly faces at the camera. Kim sported a black robe with her hair in a slicked-back bun for the occasion, while Khloé opted for a pair of Christmas-themed pajamas and wore her tresses down in loose waves.
