London, Jan 10 (Agencies): Hollywood superstar Mel Gibson is immediately seeking custody of his daughter with Oksana Grigorieva, after claiming she made false accusations about him to the press last week.

Gibson's lawyers accused the 40-year-old Russian singer of maliciously leaking false claims about her former lover and sought emergency transferral of custody of 14-month-old Lucia, reported Contactmusic.

The 55-year-old actor-director charged Grigorieva of revealing intimate stories about their sexual life and feels that such revelation is not in the best interests of his daughter.

Locked in a bitter custody battle over Lucia since April last year, the case has been referred for a hearing in February this year.

While Grigorieva has accused the 'Braveheart' star of physical and verbal abuse, his ex-wife Robyn, who was married to him for nearly 30 years, has defended him early.

"Mel never engaged in any physical abuse of any kind toward me before, during or after our marriage. Mel was a wonderful and loving father," she told the court last July.

Gibson has seven children from his marriage with Robyn.
