Chris Brown and embattled girlfriend Karrueche Tran are rumored to be on the verge of reconciling yet again in their up-and-down relationship.

According the HollywoodLife, news of the latest coupling comes just hours after the "Loyal" singer was spotted partying with former galpal Rihanna.

Brown and Tran most recently called it quits earlier this year when news leaked that he had cheated on her and fathered a child with yet another woman.

Still, Tran recently went on record in admitting that she still loves the 25-year-old crooner, and sources close to her insist she has been impressed with the way he has stepped up to be a father to his year-old daughter, Royalty.

Recently, Brown went as far as to hire a lawyer in hopes of having his name legally stamped on his daughter's birth certificate and reportedly has been paying mom, Nia Guzman, more child support than he's legally obligated to do.

"Karrueche is so proud of Chris for finally stepping up and taking care of a woman," the source told HollywoodLife. "Even if it's his own daughter. She's so proud of him for tha,t and it's refreshing for her to see that he's taking care of his responsibilities."

In addition, rumors have been percolating that Brown has been doing everything he can to win Tran back, with some reports even suggesting that he plans to propose to her on her upcoming 27th birthday.

"Chris doesn't want to lose this girl," a source previously told HollywoodLife. "She's by far the most impressive woman he's had a relationship with in his entire life. Chris is really thinking about the future and he sees Karrueche there."

But that was before he and Rihanna were recently seen partying together and even "getting a little flirty" at rapper Travis Scott's 23rd birthday party in Hollywood Hills.
