Even still-married rage-aholics need companionship. TMZ says Mel Gibson has been spending quality time with one Stella Mouzi, a Greek model and Goth enthusiast who recently made an appearance at the L.A. Fetish Film Festival Awards. Mel and Stella were spied hanging out at a Los Angeles club last week and leaving an Italian eatery earlier this month. Mouzi has also been to the star's place for a barbecue, according to TMZ, which points out that she's on a visitor's visa. Seems she hopes to stay in the U.S. a little longer because she's "into" Gibson, who has yet to finalize his divorce from wife Robyn. By the by, Mel spent Father's Day toting around 19-month-old daughter Lucia, his legal battle-beleaguered offspring with ex-girlfriend Oksana Grigorieva.
