Kim and Khloé Kardashian's reunion with Britney Spears may have come as a surprise to some - but how did it happen? A source exclusively told Us Weekly that Spears' manager, Cade Hudson, "set up the reunion" when he "reached out" to Kim, 45. "They're not that close, but they do have a lot of respect for each other because of their work ethic and their resilience in handling scrutiny," the insider shared about Kim and Khloé's connection to Spears, 43. While the trio are "not in touch often," they enjoyed a girls' night after last seeing each other "a few years" ago.
