Rob Kardashian Cheated On Adrienne Bailon

Calabasas silver spoon Rob Kardashian has confessed that he cheated on former Cheetah Girl and 3LW singer Adrienne Bailon, leading to the couple’s split last March. She blesses the guy with panty pics and this is the thanks she gets?! Rob — the younger brother of socialites Kourtney, Kim, and Khloe –dropped the bomb on Sunday night’s episode of E!’s reality docusoap, Keeping Up With The Kardashians.

Adrienne’s devotion to her career and Rob’s hectic school schedule have also been cited as mitigating factors causing the breakup. Adrienne created quite a stir in November 2008, when nude photographs she snapped for Rob were splashed on the Internet. Despite rumors of a leak, the singer claimed innocence, insisting that the photographs were taken from a laptop stolen while she was coming off a flight at New York’s JFK Airport.

Rob, 22, did not provide any details on who he was unfaithful with, although he was romantically-linked to adult film star Lisa Ann (of Nailin’ Paylin fame) as recently as November. Adrienne, for her part, has moved on. The 26-year-old New York native is currently dating an unidentified man, who she was seen texting throughout last night’s show.
