Last we heard, Rihanna was totally copacetic sharing Chris Brown with his ex-girlfriend, Karrueche Tran. But that doesn’t mean she and RiRi are friends!

The “Diamonds” singer is reportedly throwing a lavish $100,000 Halloween bash tonight, and a source tells Hollywood Life that Karrueche would be better off staying away from the spooky shindig — even  though Chris is definitely on the guest list.

“Even though Ri cool with what's going on [between the three of them] I ain’t sure if she trying to have KT all up in her party,” said the insider. “And KT don’t want to go. Ri’s crew don’t like her.”

Sounds like Karrueche might have to find her own tricks and treats tonight. Love triangles can be so complicated!
