Behati Prinsloo's Sexy Shot of Adam Levine
Moves like Jagger! Victoria's Secret model Behati Prinsloo shared this Instagram photo of fiance Adam Levine in his underwear on Aug. 28. "70s porn called," she wrote alongside the sexy snap, which shows Levine strutting down a hallway in black briefs. "It wants its vibe back. Immediately." The two had gotten engaged just one month earlier, shortly after he split from another stunner, Sports Illustrated swimsuit model Nina Agdal.
