Just who is Isaac Cohen?

Britney Spears's new guy has a hard-working agent - one who's making the most of his client's newfound fame . "He's a gentleman, he's respectful and he treats people nicely," Isaac Cohen's rep told USA Today. "He's not known to date around... They're a young couple who seem to be having a lot of fun." The 25-year-old model can currently be seen in McDonald's and Payless ads, and is "even more in demand," since he hooked up with Spears, says his rep. "He's not out to be a rapper or a dancer or an actor or anything else right now. I'm sure he will want to do something else when he gets older, but for right now, modeling is working out pretty well for him. He's got a great look."
