Mel Gibson's ex insists the actor hit and bruised their baby during alleged fight

Mel Gibson's fight with his Russian's ex took another level declaring allegations about the actor injuring the couple's infant daughter.

Oksana Grigorieva insists the "Braveheart" actor hit and bruised his 2-month-old daughter while having  an alleged episode of domestic violence on  Jan. 6 at his Malibu residence. This was reported by  RadarOnline.com.

Reportedly, Grigorieva, 40,has photo that will serve as an  evidence revealing a bruise on the baby's chin, supposedly caused by Gibson, a source told Radar.

The photos together with a number of explosive tapes are part of a sealed custody case in which Grigorieva is trying to cut Gibson's access to  their little Lucia, now 8 months old.

Reports say that the Russian singer began recording Gibson's rants to serve as  as evidence of his abusive behavior following the January altercation.

The tapes, got hold of by Radar, supposedly featured Gibson, 54, ranting and panting wildly as he orders sexual favors, gives death threats and uses racial slurs including the N-word.

In a fifth installment, the man believed to be Gibson shouts at Grigorieva and demands that she thank him for spending $5 million on her and supporting her "failed career."

"I don't have any f---ing money. I have to support you and everybody else. I have to sell paintings. I have to sell my box at the Lakers game," the man, believed to be Gibson, snarls. "I spent too much g--damn money on you, and my wife knows."

Gibson's wife for 28 years has filed for divorce last year following the surfacing of photos showing the actor playing on a beach with Grigorieva.

In another part of the secretly taped conversations, Gibson admits he struck his ex-lover as she held their daughter.

"What kind of man is that? Hitting a woman when she's holding a child in her hands?" Grigorieva asks.

"Oh, you're all angry now. You know what, you f---ing deserved it," the man says.

He threatens to bury her in a rose garden and burn the house down in other vile snippets.

A domestic violence investigation was opened by the Los Angeles County Sheriff's Department  and expects to give the case over to prosecutors next month, a representative told the Daily News.
