Kim, Khloé and Kourtney‘s brother Rob Kardashian has confessed to cheating on his ex-girlfriend, former Cheetah Girl Adrienne Bailon.

Rob admitted to straying on Keeping up with the Kardashians on E! last night, months after the couple’s March split, reports Popcrunch.

The 22-year-old didn’t say who he’d been unfaithful with, although he’s been linked to adult film star Lisa Ann.

Meanwhile, Adrienne, 26, has reportedly moved on and is dating another man.
