It's been just a few weeks since singer Adam Levine (43) drew attention to rumors of cheating. Now the Maroon 5 frontman has appeared publicly on stage for the first time – with the support of his pregnant wife Behati Prinsloo (34).

Levine performed with his band Maroon 5 at an event in Las Vegas on October 1. According to several US media, Prinsloo sat next to the stage during the concert. On the song "Sunday Morning," the singer is said to have glanced in her direction as he sang the lyrics "all I need."

Adam Levine himself commented on September 19 via Instagram story about the rumors of an alleged fling. He admitted he "crossed the line" but didn't have an affair, the singer said in the statement. "I have addressed it and taken proactive steps to work this out with my family. My wife and family are all I care about in this world." It was "naive" and "stupid" of him to risk it.

First, an Instagram model shared several screenshots of messages between herself and Levine in a TikTok video, stating she had a year-long affair with the singer. At least three other women who had received similarly salacious messages from Levine then spoke up.

Adam Levine and Namibian model Behati Prinsloo have been married since 2014 and are expecting their third child together. Prinsloo made her pregnancy public just days before the rumors broke. They are already parents to four-year-old Gio Grace and five-year-old Dusty Rose.
