The always-surprising Mel Gibson/Oksana Grigorieva saga continues: Grigorieva filed a contempt of court charge against Gibson on Thursday, RadarOnline.com reports. She claims the movie star has failed to pay the $20,000-a-month in child support he was court-ordered to provide her.

If he is found guilty at a hearing on November 10, he could face jail time or have his wages garnished.

"For three consecutive months, Mel has paid Oksana somewhere between $5000 and $10,000 each month, it varies, but either way, it is well short of what a judge instructed he must deliver the mother of his child," a source told RadarOnline.com.
