The Braveheart star, 54, has accepted the couple argued but denies assaulting the Russian pianist. But, according to Radaronline.com, new claims allege that Grigorieva has the photos to prove Gibson attacked her.
"You can see Oksana's two main front teeth were broken and there are bruises all over her face," the Sydney Morning Herald quoted an unnamed friend, who saw the photos. "They will come out eventually and she is prepared to use them in their court case," said the pal.
Grigorieva and Gibson, who split in April and share a nine-month-old daughter together, are locked in a bitter legal feud.
