Kim And Reggie On The Rocks?

Could another split be on the horizon?

Rumor has it that Kim Kardashian and Reggie Bush are heading for a break-up!

An insider on the set of 2011 Calendar Guys shoot revealed that the football player was complaining about his relationship with Kim:

“It was a two hour shoot and Reggie spent most of it texting on his phone. In between photos and costume changes, everyone on the set could tell something was going on. He became a little tense, at one point.├óΓé¼┬¥

That night Reggie was seen at Robin Thicke‘s birthday party at 1Oak in NYC where he was “flirting up a storm” with a brunette beauty.

The next day when the paparazzi asked him where Kim was he replied that he didn’t know and said “no more questions” when they asked if they were still dating!

Meanwhile Kim was sunning herself down in Miami to film Kourtney and Khloe Take Miami.

That doesn’t sound good at all — but will they call it quits for good?
