Over the past decade, Songz (real name: Tremaine Neverson) has faced multiple accusations of both physical and sexual assault.

This week, Las Vegas police confirmed it is investigating an allegation of sexual assault against Songz. The 37-year-old had been at Drai’s Nightclub in The Cromwell hotel to ring in his birthday last Saturday night. A source told TMZ that after his performance at the club, Songz and his entourage took a group of women back to his hotel room at The Cosmopolitan.

Officials would not release any further details when contacted by The Daily Beast, including exactly when the alleged attack took place, but confirmed the incident occurred in the city and was reported to the department last Sunday.

Las Vegas police said Songz was cooperating with their investigation. His team did not return a request for comment when contacted by The Daily Beast.

Songz’s track record is no secret. But for years the charming, good-looking R&B crooner, with 2010s hits such as “Na Na,” “Bottoms Up,” and “Dive In,” has managed to dodge any serious criminal repercussions for the various claims and charges brought against him.

Just this year, he was let off the hook for an incident where he was seen on security footage in a scuffle with a Kansas City police officer when he flouted repeated warnings to wear his face mask. (The county’s district attorney’s office in April declined to prosecute him, citing a lack of evidence.)
