Rihanna and Chris Brown have both been busy, and it looks like while Chris Brown has Karrueche Tran, Rihanna may have picked up a British model!

It seems that despite dating rumors between Rihanna and Drake, the "S&M" diva could now be eying model Dudley O'Shaughnessy, who appeared in Rihanna's "We Found Love" music video.

"She goes weak at the knees for him, is crazy for his accent and only has good things to say about him. Ri has been keeping her options open," says an insider to EntertainmentWise.

The irony, of course, is that many compared O'Shaughnessy's presence in "We Found Love" to be symbolic of Rihanna's relationship with Chris Brown.

But Chris Brown seems to be moving on, with his off-and-on girlfriend Karrueche Tran getting a new look, and him getting new representation along the way.

According to Billboard, Chris Brown has signed with Resolution for worldwide representation.

"Chris is a uniquely talented entertainer and we are privileged to be working with him and his team," says agent Phil Casey in a statement.

With a new album "X" expected to drop in November, Chris Brown plans to begin a world tour as well in early 2014.

Karrueche Tran, meanwhile, has dyed her hair bright red, no unlike Rihanna during her "Loud" era.

And with a duet reportedly being released on "X," are Chris Brown and Rihanna really moving, or are they simply looking for replacements of each other?
