Radar has learned the 55-year-old Bush frontman is dating 26-year-old OnlyFans star Gwen Singer.
According to insiders, the two have been hanging out a lot lately, despite their almost 30-year age gap.
Gavin and Singer's relationship comes just one month after his former wife said "I do" to Blake Shelton.
Pop culture site Deuxmoi was the first to report the news after a tipster wrote in and dropped some insight on Gavin's new romance.
"She has regularly posted at his house," the tipster wrote, adding she's often shared "meals he's made for her."
The insider also claimed they even shared a "sweet moment" on the beach in Malibu, CA, where Gavin lives.
Singer has 1.3 million Instagram followers, which is one million more followers than Gavin has.
Not only are the duo following each other, but Gavin is also shooting his shot by liking Singer's super sexy photos.
In fact, the musician has been showing her love on social media for at least four weeks. The young brunette bombshell shared a series of busty shots on July 22 and Gavin couldn't wait to double tap.
In the photos, Singer is seen going braless and wearing the tiniest denim shorts imaginable. "Today’s forecast: 100% chance of nip-slip," she teased.
Singer isn't just a favorite on Instagram. She's also popular on OnlyFans. For those living under a rock, OnlyFans is a paid-for content site where creators show a little more skin than usual.
Gavin's new lady has nearly 100,000 likes on her OnlyFans photos, and for just $10 per month, you can get access to her private photos.
The rocker's relationship comes just one month after his ex-wife married Shelton in a private ceremony that was so small, their dearest friends weren't invited.
“Adam had no idea when Gwen and Blake very going to get married. Adam wasn’t invited to the wedding and was not given the heads up despite the fact that Blake and Adam used to be as close as brothers when they were both on The Voice together,” our insiders said at the time.
Following their wedding, Stefani and Gavin had an icy reunion at one of their kids' games.
The former couple wed in 2002 and ended their marriage in 2016. Stefani and Gavin share three children together — Kingston, 15, Zuma, 12, and Apollo, 7.
