Former Cheetah Girl and 3LW singer Adrienne Bailon had to relive a sour moment last week thanks to reality television. On the Jan. 3 episode of 'Keeping Up With the Kardashians,' Bailon's former flame Robert Kardashian admitted that the two ended their two-year romance in 2008 due to his infidelity. Even her labelmate and rumored fling, Fabolous, took to his Twitter during the show's airing. "Am I the only one that doesn't watch the 'Kardashians' show?" he tweeted. "I don't know what's goin' on but Adrienne's phone is blowin up 2nite."



During the previously taped show, Robert, 23, was visibly remorseful yet did not disclose details of the woman he cheated with. The younger brother to Kim, Khloe and Kourtney appeared with Bailon on the E! reality series several times during their relationship. Discussions of his sketchy behavior were never hinted at when Adrienne, now an artist signed to Def Jam, made regular appearances on the show last year. Instead, the couple was shown to be deeply enthralled with one another, and as a result, Robert inked his left rib cage with a tattoo of Adrienne's name. So much for that tattoo.
