Mental Mel Ready To Explode!

Mel Gibson could be headed for the psych ward after a series of escalating bizarre outbursts that have friends worried, The National ENQUIRER has learned.

Mel’s girlfriend, Rosalind Ross, was with the infamously hotheaded star when he launched into his latest meltdown, allegedly verbally and physically attacking a female photographer in Sydney!

“It looks like he’s spiraling out of control again,” an insider told The ENQUIRER.

Rosalind, 24, an aspiring screenwriter, is now begging Mel, 59, to start anger management sessions, the insider said. Veteran photographer Kristi Miller, who works for The Daily Telegraph, claimed Mel pushed and verbally abused her outside a movie theater Aug. 23.

“I thought he was going to punch me in the face,” Kristi, a mother of three, alleged. “He was spitting in my face as he was yelling, calling me a dog, saying I’m not even a human being and I will go to hell,” she recounted.

“He swore and called me the C-word. It was nonstop; he didn’t even breathe.”

Mad Mel only calmed down when Rosalind intervened.

The “Lethal Weapon” star reportedly went ballistic after Kristi photographed him and Rosalind walking, but Mel’s rep later claimed he only reacted because he was being “harassed.”
