Maroon 5 frontman Adam Levine is dating model Nina Agdal, according to a U.S. report.

The 33-year-old rocker, who was said to be in a relationship with Namibian beauty Behati Prinsloo last year (12), has been romancing Sports Illustrated star Agdal, 21, for several months, according to editors at UsWeekly magazine.

A source tells the publication, "Behati was in and out, but they finally ended it. It wasn't an abrupt ending."

The report suggests Agdal has been seen on the set of the U.S. version of talent show The Voice - on which Levine is a coach - in recent weeks and they are preparing to go public with their romance.

The source adds, "Nina is happy she can be open and not hide anymore."
