Rihanna has reportedly defended her former boyfriend Chris Brown by calling his recent ex-girlfriend Karrueche Tran “tacky and childish” for slamming the “Loyal” singer on social media. The news comes after reports surfaced that Brown and Rihanna appeared to have come to good terms after their tumultuous relationship ended in 2013.

“Rihanna doesn’t really know Karrueche all like that and doesn’t walk in her shoes,” a source told Hollywood Life. “But from her outside perspective, she feels she goes too hard on him [Brown] and let’s the world in on their business on social media. That’s just tacky and childish! Ri thinks Karrueche needs to give that boy a break.”

Tran broke up with Brown after she discovered that he had a child with model Nia Guzman. In a post on her Instagram account earlier this month, Tran slammed Brown saying that her relationship with the singer ended because of his “lack of loyalty.” She also called Brown “weak” and asked him to “man up.”

Amid Brown's issues with Tran, he and Rihanna are reportedly getting over their own past troubles, six years after he assaulted her.

Rihanna reportedly watched Brown’s rehearsal for his performance at the BET Awards on Sunday. And though Rihanna did not walk the red carpet as she wanted to avoid a run-in with Brown, she reportedly supported him in private.

“Rihanna didn’t walk the red carpet, but she did see Chris backstage to watch his rehearsal,” another source told Hollywood Life. “It was very brief and absolutely no one was allowed back there to see them. She told him to have a good show, watched about a minute or two of the rehearsal, and then left.” She “wanted to tell Chris how proud she is of him. After everything he’s gone through, he’s still pushing forward, making music and the best part is -- he’s a proud father.”

 The “Unfaithful” singer also reportedly got emotional when she heard Brown talk about his daughter Royalty in his speech while accepting two BET awards.

“Seeing Chris’ eyes light up and hearing him talk with so much energy and passion about Royalty turns Rihanna on,” a third source told Hollywood Life. “It makes her so happy and her heart skips a beat. She thinks it’s so beautiful and admirable. She feels he’s maturing right before her very eyes. She knows he’s going to be a great dad. That little Royalty is in good hands.”
