Some girls blame their mothers for their hips, thighs, and butt, but not Kelly Osbourne. "I have a mustache because of my mom," she reveals.
But it's not because of genetics -- the former reality star and "Dancing With the Stars" contestant told talk show host George Lopez that her lip locks were the result of a waxing gone awry.
"When I was a kid, she got a home waxing kit, and I was the crash-test dummy," she said of mom Sharon Osbourne. "The wax was so hot that it burned me... By the time she pulled the wax off, my skin went with it, and I had to go to school with a scab mustache."
While the incident didn't leave a scar, it did create a hairy situation. "Now I have a mustache that I have to wax that I blame my mom for!" said 25-year-old Osbourne, who wore a slinky black dress that flaunted her super-slender figure, a result of her stint on "DWTS" last season.
"That show did amazing things for me, and I never thought that I would discover who I was through a dancing show," she said. "Louis van Amstel, my dance partner, completely changed my life. He got me eating healthy, he got me to lose weight, and then I thought, if I've gone this far, I might as well go all the way."
Now, Osbourne is showing off her newfound confidence by co-hosting E!'s "Fashion Police" alongside cutting comedienne Joan Rivers, though, she told Lopez, "I will not f--- with her. There is no way. There is no way. She's so quick and she's got a tongue like razor blades!"
