Jackson Family -- The Burial After-Party

TMZ has learned the Jackson family has an after-party scheduled to begin right after Michael Jackson's funeral tonight -- a party they're calling a "Celebration of Life."

The family will go straight from the Forest Lawn cemetery in Glendale to a place called Villa Sorriso Ristorante -- an Italian joint in Pasadena.

The restaurant's Executive Director of Operations has confirmed that Randy Jackson made the reservation several days ago and "bought out the facility for the night."

The exec also tells us several members of the Jackson family have been regulars at the place for years.

We're told the restaurant is expecting around 275-300 people to attend.
