Singer Adam Levine is collecting supermodels like pez dispensers. The Maroon 5 frontman is reportedly dating Sports Illustrated model Nina Agdal.

According to UsWeekly, the 33-year-old rocker and the Danish model, 21, have been dating for several months. She has even been spotted on the set of "The Voice," in which Levine is a mentor.

The couple plan to go public with their romance. An insider explained:  "Nina is happy she can be open and not hide anymore."

Levine was linked to Victoria's Secret beauty Behati Prinsloo last year. A source told the magazine: "Behati was in and out, but they finally ended it. It wasn't an abrupt ending."

Prior to that, Levine dated model Anne Vyalitsyna, also a Victoria's Secret and Sports Illustrated model.

Levine recently talked about his distaste for drugs after a bad experience with prescription medication Ambien.
