Chris Brown is feeling "hurt" after learning about the rumored romance between Rihanna and Leonardo DiCaprio, Hollywood Life reported Tuesday. Rihanna and DiCaprio fuelled dating rumors after they were spotted together at an opening of a Las Vegas nightclub over the weekend.

“Chris thought Rihanna was done playing around with bad boys who don’t want to commit. He was stunned a little bit to hear she’s her backin Leo’s arms and whispering in his ear. That hurt him a bit because he still has feelings for her,” a source told Hollywood Life.

“As a former bad boy himself, Chris changed his entire image and persona, mostly for Royalty, but partly for RiRi too,” the source added. “He loves Rihanna and no disrespect to Leo, but he doesn’t want Ri to get caught in his glory just because he recently won an Oscar. Leo’s still a player and he hopes she knows that.”

Dating rumors between Rihanna and DiCaprio heated up after the two were spotted getting cozy last week at a Coachella Valley & Music Festival after-party.

Entertainment Tonight reported, citing an eye-witness, that the “Diamonds” singer walked to the VIP section of the Intrigue Nightclub at Wynn Las Vegas casino hotel, where she was seen having a chat with DiCaprio. The source reportedly said the two were “whispering into each other’s ears.”

Brown and Rihanna's relationship ended after the 2009 incident when he physically attacked the "Needed Me" singer ahead of the Grammy Awards.

Recently, Brown addressed the assault in a clip for his upcoming documentary, "Welcome to My Life," admitting that he once contemplated suicide after the incident. “I went from being on top of the world — No. 1 songs, being kind of like America’s sweetheart — to being public enemy No. 1,” Brown said.
