But the source added Rihanna has agreed to the ban if Chriss ex, Vietnamese model KARRUECHE TRAN, is also barred.

The last time Chris had a go at one of Rihannas exes was when he bumped into Drake at a New York club and the place was trashed in a brawl.

A$AP will be hoping plastic glasses will be handed out at the reception if Rihanna manages to get him a wedding invite.
