US Weekly posted a clip from the upcoming episode of Keeping Up With the Kardashians, which airs Sunday at 10 p.m. (EST) on E!

In the clip we can hear Kim Kardashian’s ex, Reggie Bush, going off on her after reading reports of her dating a NFL player Miles Austin.

“It is what it is. You’re on your own now,” Bush tells Kim who put him on speaker phone for the world to hear. “It’s literally f***ing driving me crazy!” he rants.

As you know Kim recently dumped Miles. But why was Reggie so upset? Is it because Reggie never fully got over Kim? Or is he one of those brothas who don’t want to be with a chick, but he doesn’t want her to sleep with anyone else either?
