Report: Mel Gibson to Appear in Court Monday

In the latest chapter of the Mel Gibson-Oksana Grigorieva saga, it seems the Oscar winner remains adamant about removing his 1-year-old daughter Lucia from the custody of her mother. And he reportedly intends to stand up in L.A. County Superior Court tomorrow to pursue his mission.

Grigorieva's recent CNN interview with Larry King has infuriated Gibson, according to TMZ. The new report says the 54-year-old father of eight wants the judge in the couple's custody battle (who had warned Grigorieva not to talk to the media) to respond. On Monday he hopes to show the court how serious he is about stripping his ex of her rights when he appears before the bench in person seeking full custody.

For the next six months, Gibson allegedly wants Grigorieva to have only supervised visits with no overnight visitation, on the grounds that her recent behavior "smacks of instability."

In recent days, TMZ says Gibson nearly called police when Grigorieva was two hours late in transferring their young daughter to Gibson's nanny, who had arrived for a 10:00 a.m. pickup but wasn't handed the child until noon. Apparently the score-keeping between the two parents is intense: a source says Grigorieva was merely making up for a previous exchange when Gibson's nanny was late in returning Lucia home to her mother.

While he was clearly a rage-filled handful of a partner (he has denied hitting, but has admitted to slapping, Grigorieva), at least Gibson has been described by his ex as a "great" father, according to recent testimony by the star's longtime publicist. The night before his ex-girlfriend's incriminating Larry King interview was broadcast, he and ex-wife Robyn celebrated their son's 21st birthday at a hotspot in Hollywood.
