Celine Dion once halted a show in Las Vegas when a brawl broke out in the audience.

The Canadian singer is celebrating the 10th anniversary of her residency at Caesars Palace and she admits one of the most memorable gigs involved a fight in the audience.

She explains, "It turned out to be almost a bloody fight. I thought they (fans) were all going to the bathroom. I started to see a few people standing... and then I started to hear things and so I stopped the band. I was scared a little bit."

Dion is still not clear as to why the scrap started but she believes one devotee got annoyed with another when he kept blocking his view of the stage while taking photos of the singer.

Thankfully, most of Dion's shows are drama free. She adds, "Normally it goes pretty smoothly."
