Mel Gibson may have to pay a substantial amount of child support to ex-girlfriend Oksana Grigorieva for their five-month-old daughter, Lucia, following their recent breakup.
Between Kelis, Shawn Southwick, and now Oksana, it looks like golddiggers are having the best month ever.

Although the controversial Oscar winner has not confirmed it, reports surfaced last week claiming Gibson had ended his year-long romance with the mother of his eighth child. Mel began dating Oksana just weeks before announcing his split for wife of 30 years Robin Gibson last March. According to family law attorney Steven Knowles, Gibson may have to shell out $12,000 to $15,000 a month to the Russian singer Grigorieva for their daughter, but probably has no legal responsibility to make alimony payments to Grigorieva because the pair never married.
“This is not dissolution of marriage action. The mother would have rights to child support, which in the case of Mr. Gibson, will be very substantial,” Knowles told PEOPLE this weekend. “He is what we call a high-income earner, and there is a high-income earner stipulation that says they must pay any amount reasonably necessary for the support of the child. Merely living together and having a child does not give the mother any rights to property and certainly no spousal support.”
