Karrueche Tran vs. Rihanna 'beef' intensifies: Model's 'best friend' Christina Milian parties with Chris Brown's ex & boyfriend Drake

A huge cat fight could have erupted at LA's infamous Supperclub earlier this week, but thankfully everyone kept their cool!

Rihanna and Karrueche Tran are still heated "frenemies" - and both beauties were spotted partying at the Hollywood hotspot on Tuesday evening (April 8). Thankfully, Chris Brown's on-and-off again model girlfriend decided to leave the club right as RiRi was arriving, in order to avoid any drama.

An insider for HollywoodLife insists that neither starlet wants an awkward comfrontation:

"Rihanna wasn't about trouble or drama and homegirl knew that and did the best thing she could for her and her friends - and that was to bounce, immediately!"

The source continues, "Everybody in town knows Rihanna helped put Greystone on the map, that's her home away from home... She's royalty there. No disrespect but other bi**hes need to know their place and all will be well, as evidenced by last night."

But fellow songstress Christina Milian (allegedly one of Tran's "BFFs") doesn't want anything to do with this ongoing love feud. She was also spotted at the Supperclub on Tuesday, and didn't bother to ignore RiRi or her boyfriend, rapper Drake!

Wonder if this upset Tran? Check out some photos from the star-studded evening here.

Drizzy even placed a huge kiss on the "AM to PM" hitmaker's cheek.

Apparently some people are sick of taking sides in the Team RiRi vs. Team Tran debacle. Should Breezy's exes just let things go and call a truce already?
