Oksana Grigorieva is to receive an increase of $15,000 a month from ex-boyfriend Mel Gibson.

The Russian singer - who split from the actor amid claims he attacked her while the couple’s 11-month-old daughter Lucia was in her arms - will now receive a total of $20,000 per month in child support payments from the 54-year-old star.

According to gossip website TMZ, Judge Scott Gordon, who is presiding over the couple’s custody battle, issued an order yesterday afternoon to raise Mel’s maintenance payments. However, Oksana is likely to be disappointed with the ruling, after reportedly requesting $60,000 a month from her former partner.
