Rocker Travis Barker's outspoken ex-wife has publicly apologized to socialite Khloe Kardashian after calling her a "donkey" on television.

Shanna Moakler was talking about Kardashian's recent wedding to basketball star Lamar Odom on the "Wendy Williams Show" on Tuesday when she let rip with her thoughts about the newlywed fellow reality TV star.

But after Kardashian responded to the former beauty queen via Twitter.com, admitting she had no idea "who this girl is" Moakler took to her Twitter.com to say sorry.

She wrote, "You are right. We don't know each other personally and I apologize for my comment this morning."
