Gibson delaying release of Grigorieva CD?

Mel Gibson has reportedly delayed the release of former partner Oksana Grigorieva's new CD.

The Oscar winner executive produced the LP and co-wrote some of the songs. Gibson also holds some of the publishing rights, according to TMZ.

However, Grigorieva cannot release the album, called Beautiful Heartache, without Gibson's written approval.

Gibson is currently involved in a bitter and public domestic violence investigation with Grigorieva.
