Rihanna has moved on from Chris Brown - she developed a crush on Grey's Anatomy's Jesse Williams after he appeared in her latest music video.

The actor, who played Dr. Jackson Avery on the hit U.S. show, starred opposite the Bajan beauty in the promo for her new single Russian Roulette.

And ever since they wrapped filming, Rihanna, who famously split from the Kiss Kiss hitmaker after he attacked her in February, has been swooning over Williams.

When asked about her crushes, Rihanna said, "Well, there's this actor. His name is Jesse Williams. He was in Grey's Anatomy and I have him in my video for Russian Roulette. He's so hot."
