Bittany will be interred in the Bright Eternity section and the guest list includes approximately 20 people.
Scheduled to attend from Hollywood are actor Eric Balfour and Penny Marshall.
The service itself will be co-denominational - there will be a rabbi and a pastor present.
The family, absolutely devastated and still in shock from Brittany's sudden passing, chose Amazing Grace to be sung at the graveside.
