Justin Bieber fans have jumped to the singer's defense after he was accused of shouting at his wife Hailey in public.

Footage of the alleged exchange was filmed at a Las Vegas nightclub on Saturday, July 10, and shows Bieber seemingly shouting at his wife as they stand surrounded by their security team, Metro reports.

The 'Baby' singer, 27, can be seen wearing a green shirt as she speaks in an animated way at Hailey, 24, and gestures to her with his hand.

However, eyewitnesses have claimed that he was simply excited after having performed in the city earlier that evening.

One witness claimed: "I took this of Justin right before that video was taken. He was on STRAIGHT adrenaline from performing. He wasn't mad at Hailey and he wasn't yelling at her. I hate how he's always painted as the bad guy when he's the furthest thing from it."

This was backed up by a source who told E! News that Justin was excited to have the opportunity to perform at the new venue, Delilah, at the Wynn Las Vegas.

Other fans of the singer were quick to jump to his defense.

A second added: "Mind your business, however he talks to her is their business, I'll be damned if someone tries to come at me about how my wife talks to me or how I talk to her during an argument, come catch these hands [sic]."

A third wrote: "I dont [sic] think he was yelling at her. It looked more like he was yelling about something. People read to [sic] much into stuff."

A fourth added: "They don't seem to be yelling, as in mad at each other. People are screaming all over the place. He is probably talking loud so she can hear him."

A fifth, meanwhile, said that it didn't matter even if they were arguing.

They wrote: "BIG DEAL. I dont know a husband and wife that dont yell at each other from time to time. If you dont, you have not been married very long and the honeymoon stage is still going. People need to mind their own business [sic]."
