Adam Rodriguez, who played Eric Delko on CSI: Miami for seven years, is set to come aboard Ugly Betty.

The actor will play Bobby, an ex-boyfriend of Betty's sister Hilda.

"He's an old high school boyfriend, and  [he comes] back into their lives," Rodriguez told TV Guide. "A little romance buds, and there's some drama to go along with it."

But who will be involved in this romance,  Hilda or Betty? The actor wouldn't say.

"Maybe a little bit of both. We'll see how it turns out, but it's going to be a lot of fun and it's really funny," said Rodriguez, who appears in at least five episodes.

Ugly Betty also made male viewers happier this summer: it cast Brooklyn Decker in a guest-starring role.
