Is there trouble in paradise for Maroon 5 frontman Adam Levine and his Victoria’s Secret Angel girlfriend Behati Prinsloo? Rumors are the romance may be fizzling after he brought his mom as a date to the Grammys. But we’re told that while Prinsloo was a no-show for the band’s concert at Madison Square Garden on Saturday, they did meet up afterward. Levine formerly dated VS Angel Anne V. Reps for Levine and Prinsloo did not respond for comment last night.
