London, Aug 4 - Actor Mel Gibson wants a change in the custody agreement with Russian singer Oksana Grigorieva over their 21-month-old daughter Lucia as he wants to spend more time with the child.

Gibson, who split with Oksana last year, has filed a request with a court to request additional overnight stays with Lucia, reports TMZ. com.

Currently, the 55-year-old actor is allowed three overnight stays every two weeks with his youngest child, who he had with the Russian singer.

However, nothing will be decided until a hearing in September. (IANS)
