Chris Rock's ex wants custody of kids

Chris Rock's estranged wife Malaak Compton-Rock reportedly wants sole custody of their two daughters.

The 49-year-old comedian filed for divorce from Malaak Compton-Rock last week after 19 years of marriage and she reportedly wants to stop him from seeing their daughters Lola Simone, 12, and Zahra Savannah, 10.

A source close to Chris - who wants shared legal and physical custody - said: ''He lives for his children. They come first. When he was doing a publicity tour for 'Top Five,' he made it clear it had to be scheduled around being able to take his daughters to school and pick them up.''

Chris and Malaak, 45, did sign a pre-nuptial agreement in 1996 but it could be a ''key battleground'' in their divorce as it may have expired because it was created so long ago, with the 'Top Five' star arguing it became void after 18 years of marriage.

Though the couple have only just announced their separation, insiders say they had been having problems for ''some time''. The source told the New York Post newspaper's Page Six column: ''Chris just wasn't happy in the marriage anymore.

There is no third party involved . . . Chris and his wife had previously separated and got back together, so there have been problems for some time.''
