Feisty singer Christina Aguilera decided to deal with Kelly Osbourne's constant taunts about her directly - by getting violent with the rock teen.
'Dirrty' star Aguilera, 22, has long been a victim of 18-year-old Kelly's criticism and she most notably referred to the raunchy singer as "one of the most disgusting human beings on the world" in a recent interview.
But the two hadn't met until OZZY OSBOURNE's outspoken daughter walked into a Hollywood party shortly after the comments surfaced.
According to fellow revelers, Christina immediately dashed for Kelly and jerked her into a headlock.
A source tells American tabloid the Star that a furious Christina hissed, "If you've got something to say, say it now!"
Normally brash Kelly was so scared that she couldn't talk and when Christina finally let go, she warned, "If you ever wanna tell me something, tell me in person!"
