The Kim Kardashian/Kanye West wedding might get a little awkward. Rachel Roy has, according to "Us" magazine, RSVP'd yes to the European bash, along with Jay Z. Why's that a problem? According to sources, it was Roy that caused the fight between Jay and Solange Knowles.

The rapper reportedly was talking to Roy and that did not sit well with Solange. "Solange yelled about Rachel on Beyonce's behalf, asking Jay, 'How could you treat my sister like that?'" the source says. "Solange walked up and started screaming at Rachel. She was making a big scene."

For her part, another source says Roy and Jay Z didn't even speak that night. It hasn't be confirmed in Beyonce will attend the ceremony, but just in case, Kimye should keep Solange far away.
