Brown, who recently broke up with his girlfriend of a year over his friendship with ex Rihanna, thinks it is better if they don't contact each other anymore, reported Hollywood Life.
"They not talking. Ain't no shade though, he just wants to be done with it and I know Rihanna does too. It's best for everybody, even Karrueche. The last thing he wants to do is get her caught up again," a source said.
The only contact they had was when Brown helped Tran move out of his home last week.
"He is not talking with her - other than to set up times for her to come get her set but that was last week. She still got a few things at the crib."
