During their heated argument where Mel Gibson punched Oksana Grigorieva with 2-month-old Lucia in her hands, the baby was hurt.
Oksana has a picture of the newborn with a bruise on her chin, which is exactly the evidence she needs when going to court next Thursday for her custody battle.
“The photos show a small bruise on Lucia’s chin,” claims a source.
We hope Mel isn't allowed anywhere near that child!
