Adam's on to his next supermodel girlfriend

No one could have seen this one coming -- not!

After ending things with Victoria's Secret Angel Behati Prinsloo, Maroon 5's Adam Levine is already on to his next supermodel girlfriend. This month's lucky winner? Twenty-one-year-old Sports Illustrated model Nina Agdal.

The two have been dating since early spring, sources tell Us Weekly, and Adam is "having fun." Well, who wouldn't be with a swimsuit model on his arm?

A source tells Us that "Nina is happy she can be open and not hide anymore." I guess as long as she's happy -- and knows that Adam's a notorious model-izer.

The 34-year-old has a past rife with models. Before Behati it was Victoria's Secret's Anne Vyalitsyna, whom "The Voice" mentor dated for two years.

His other past model girlfriends include Victoria's Secret Angel Erin Heatherton, German-born Janine Habeck and VS' Angela Bellotte.

Granted, not all of Adam's girlfriends have been models, but he's definitely been on a model streak lately. Wonder who'll be next ...

Michelle to play Marina Oswald in 'Killing Kennedy'

After starring as mean girl Georgina Sparks in the CW series "Gossip Girl," Michelle Trachtenberg is taking on a more serious role for her next acting gig. She will be portraying Lee Harvey Oswald's wife, Marina, in the upcoming National Geographic TV movie "Killing Kennedy," which is based on Bill O'Reilly and Martin Dugard's best-selling book of the same name.

The 27-year-old Michelle is charged with playing the Russian-born Marina, who has held that her deceased husband is innocent in the killing of President Kennedy.

"I am so excited for the challenge to portray Marina Oswald and to do my first role speaking only in Russian," Michelle told Us Weekly. "I'm the only actor playing someone who is still alive, so I want to stay as true to her as possible. This is a story about JFK's assassin, Lee Harvey Oswald and his wife, Marina. And it is fascinating."

Production will begin next month, according to the Hollywood Reporter.

Say what?

"I love and respect that he's honest enough to say, 'Yes, I did this. It was my fault.' He's a real man. Most people would hide, and he doesn't. It doesn't make me love him any less. It took a long time to get to that place, but I understand it now. And my mother does, too." - Kelly Osbourne, speaking to Cosmopolitan about father Ozzy's recent confession that he'd been taking drugs and drinking for the past year and a half
