As you've no doubt heard, last month an 

Instagram model named Sumner Stroh alleged she and the She Will Be Loved singer had an affair for about a year. Disgustingly, she added that he'd reached out after they ended things to tell her he wanted to name his unborn child with wife Behati Prinsloo after her. Ew. Stroh's receipts were quickly backed up by other women who said Adam had hit on them online — or in some cases even sexted with them.

However, he flatly denied ever having an affair — a physical, in-person affair — and from what we've heard Behati believed him! The supermodel has stayed by his side.

Oh, and he announced a Vegas residency — so career-wise he's doing just fine, too. It really seemed like he was skating away from the scandal scot-free.

According to a source spilling to RadarOnline on Thursday, Gwen Stefani is demanding hubby Blake Shelton cut ties with his former rival/BFF from The Voice. While others might be willing to forgive and forget, the No Doubt frontwoman is standing firm on cheating. The insider said:

"For her it's personal. She isn't worried about Adam being a bad influence [on Blake], this is about principle.

"

 Adam notably wasn't at Gwen and Blake's wedding, but then again who was, right? This insider says Blake and Adam weren't exactly the BFFs they seemed on the show anyway:

"It wasn't all an act, but the relationship was exaggerated for TV. When Adam left the show the two of them didn't have to pretend anymore. They haven't spoken in a while. There was no big dramatic falling out, but they both just moved on. It happens all the time with work relationships."
