Things are really getting heated and physical on 'The Voice.' Literally.

Perez Hilton reports that on this week's episode of the highly rated, reality competition series, coach Christina Aguilera, who is known for her warm demeanor towards hopefuls and for bestowing hugs on the talent she chooses for her team, had to call security because she was attacked by one of the contestant's family members!

Apparently, here's a loose account of what went down: There was a sing-off between Tarralyn Ramsey and Frenchie Davis, the latter of which is a former 'American Idol' contestant from a few years back as well as a Broadway singer, so if her name rings a bell, that's why. Things got tense after the two sang Beyonce's 'Single Ladies (Put a Ring On It)' and a family member attacked Xtina. It was not clear whose family member felt the need to go after Aguilera, either.

It has not been determined if the attack will be shown on tonight's episode, which airs at 10PM ET on NBC. Be sure and watch to see if the raucous is aired. The show is pulling in massive ratings, so it's not like it needs a publicity stunt to generate interest, which makes us that much more curious about what the hell happened.

There is video footage of the sing-off but any attack on Aguilera is not visible in the clip.
