Chris Brown warns Ashton Kutcher off Rihanna

Rihanna has been making headlines lately with her antics, and now her ex Chris Brown has apparently warned her rumoured love interest, Ashton Kutcher, to back off.Rihanna

Tale Tela reported: "Sources now say that Ashton backed off after receiving warnings from RiRi's ex Chris and friend Diddy. At first, Ashton took it as a joke," the source continued, "but Diddy told him that Chris was dead serious and really worked up about the idea that Rihanna has moved on."

Rihanna, naturally, was not pleased with Chris Brown's interference. According to the site, the Bajan beauty "was so angry after learning of his challenge to Ashton, she called her jealous ex and told him to back off."

The tables seem to have turned dramatically, as a recent article claimes: "Chris Brown Says Rihanna Is Making An Ugly Spectacle Of Herself." Celeb Dirty Laundry claimed that Chris sent Rihanna a private message in which he told her to step back and stop sending nasty tweets about him and his girlfriend Karrueche.

"Rihanna has overstepped the limit with Chris Brown," Celeb Dirty Laundry wrote, "and he is speaking up and saying that he is well and truly sick of her."
