A disturbing photo of Mel Gibson's ex Oksana Grigorieva has hit the web.
RadarOnline reports the shot was taken after the Russian singer, 40, got into a heated fight with Gibson, 54, Jan. 6.
The photo shows Grigorieva with two damaged upper front teeth.
A source tells Radar that Grigorieva lost a veneer and her right front tooth was severely chipped during the fight, which allegedly occurred while she was holding their 8-1/2 month-old daughter Lucia.
A Gibson source tells UsMagazine.com that, although they did argue that day, it didn't turn physical.
Says the source, "They got into, but he absolutely did not injure her."
Gibson and Grigorieva are currently engaged in an increasingly ugly custody dispute over their daughter, Lucia.
Sources tell Us that Grigorieva's claims are a ploy for more custody — and cash. (His lawyer Stephen Kolodny tells Us the duo had reached an agreement in May that would lead to fifty-fifty custody.)
Nevertheless, detectives at the Los Angeles County Sheriff's Department are currently investigating the incident. Detectives hope to speak to Gibson, who has yet to be interviewed.
Still no word if the case will be turned over to prosecutors, who will decide whether Gibson should face criminal charges.
Over the past few days, Radar has posted a series of profanity-laced recorded arguments, apparently between Gibson and Grigorieva.
The tapes paint Gibson as a racist, violent man.
According to TMZ, Gibson's lawyers claim Grigorieva demanded more than $10 million to keep the rants a secret.
Her rep has denied that she leaked them. Her rep also says claims that the tapes were edited are "ridiculous."
