from www.msnbc.com – While it’s Mel Gibson’s allegedly violent and racist rants against ex-girlfriend Oksana Grigorieva that made the rumor rounds lately, another woman maintains she had her own first-hand experience with the star’s bad behavior.

Adult film actress Violet Kowal, who claims she shared a brief romance with Gibson while he was seeing Grigorieva, told The Mirror that the actor-director seemed the perfect gentleman when they first met.

“At first he was charming,” Kowal revealed. “He was very complimentary and told me he was attracted to me. He came across as a single man. It was only later I realized he was seeing me behind Oksana’s back.”

Being the other woman while Gibson dated his — well, other other woman — wasn’t really a problem for Kowal. That is until things took a turn for the worst.

“At first he was always in a good mood, then I got to see his temper,” Kowal said. “It’s really scary — he can go from smiling one minute to furious the next for no reason at all.”

Then, on the same January day Grigorieva claims Gibson struck her, Kowal said she had her own unexpected falling out with the A-lister.

“(Mel) called me up from a blocked number so I wouldn’t know it was him,” Kowal recalled. “I picked up the call and he screamed at me ‘Listen you bitch, do you know who this is. Don’t f— with me or I will make you suffer.’ Then he hung up. I was crying and shaking — terrified because he knew where I lived. I had no idea what he would do to me but I’d seen his temper before. I packed my stuff and left town for a few weeks.”

According to The Mirror, Gibson’s rep dismissed the allegations as “an absurd fabrication,” which is just what Team Mel told the National Enquirer when Kowal first discussed the relationship back in March.
