Adam Levine dating SI model Nina Agdal

Sports Illustrated model and prom heroine Nina Agdal is reportedly Adam Levine's latest squeeze.

The Maroon 5 singer has been dating Agdal since early spring, sources told Us Weekly, after ending his one-year on again-off again relationship with Victoria's Secret Angel Behati Prinsloo.

"Behati was in and out, but they finally ended it," a source close to Levine said. "It wasn't an abrupt ending."

As for Agdal? "It's still new," the source said. Levine, 33, is "having fun again."

Agdal, 21, was spotted on the set of "The Voice" last week, and attended a live taping Monday. She recently stepped in to attend a prom with teen Jake Davidson, after Kate Upton wasn't able to make the date.
