Two of music's most outspoken women just keep on throwing punches at each other. Courtney Love vehemently denies Sharon Osbourne's claims that she introduced Osbourne's son, Jack, to OxyContin. "I never did that. I would never give drugs to a teenager. F--- you, Sharon -- as if I would ever give drugs to a teenager," Love said last week in London.

Today, Osbourne fired back, telling the New York Daily News, "I'm glad she doesn't like me. I only pity her. She's a virus. I don't want her anywhere near people I love. The cold, hard fact is she's a has-been."

In September, Osbourne told Britain's Daily Mirror newspaper, "I will never have time for Courtney Love. She was the first person to give my son Jack the prescription drug OxyContin. There's not a shadow of doubt in my mind about that."

"My dislike towards her is very personal," Osbourne continued. "I'm not saying Jack wouldn't have taken it if she hadn't given it to him, but I'm appalled that an adult mother would give that to a 15-year-old boy. How could she do that to someone else's child?"

Love asserts she had never heard of OxyContin until she met Jack. She added, "It was the first time I was ever introduced to the pills." Jack's use of the painkillers landed him in rehab in 2003. He's been clean since, and he recently wrote an autobiography called '21 Years Gone.'
