Oh no! Did Justin Bieber go berserk at a pre-Grammys party over the weekend? Based on the latest reports, Selena Gomez’s ex-boyfriend head-butted a guest early Saturday morning when a confrontation escalated after Bieber saw him taking a video of the singer’s “play fight” with pal Kyle Massey.

Bieber, who was also feuding with Gomez’s current beau The Weeknd, has recently made headlines for all the wrong reasons. And now, Entertainment Tonight reported that the 22-year-old “Love Yourself” singer is being investigated for a “head-butting” incident at a restaurant called Serafina in Los Angeles on Feb. 11.

“There is an open investigation where someone inside the establishment called and said that something happened with him [Bieber] outside," the Los Angeles County Sheriff's department told the publication.

What really transpired during the said incident, however, remained uncertain. In fact, the authorities have yet to confirm if Bieber was really involved in the battery case. The singer’s camp has yet to release any comments or statements as well.

Bieber’s battery case reports emerged when TMZ ran an article about the incident involving the “What Do You Mean” crooner who allegedly beating a man at a party. According to the publication, Bieber got upset when somebody recorded his “play fighting” with former Disney actor and friend Massey at 2 a.m. EST on Saturday.

Bieber reportedly asked the man to delete the video. However, when the latter refused, the tension escalated and the singer head-butted him, causing the other attendees to call law enforcement to the scene. But when the authorities arrived, Bieber had already left the premises.

Meanwhile, a representative for Serafina restaurant told the publication that no one from their staff was involved in the incident or called 911. Police then said that the person who reported the incident was not the victim.

“We know very little about the alleged incident at Serafina Sunset with Justin Bieber, but we can assure you that nobody from our staff was involved, nor did we call the police,” Serafina Restaurant Group’s Director of Public Relations Caroline McBride said. “We always have pleasant experiences with Mr. Bieber whenever he comes to Serafina.”

In other related news, Bieber’s ex-girlfriend has released a new breakup song, titled “It Ain’t Me.” According to Elle, the single was her collaboration with Kygo. Gomez apparently co-wrote the song, which speaks about a guy she met when she was 17, the same age she had been when she met Bieber in 2009. But as the magazine noted, the song seemed to be Gomez’s way of telling Bieber that things between them are really over.
