Tompkins and Bush have worked with the King of Pop for the last 20 years and had been designing costumes for Michael's planned "This Is It" concert series in London.
A private family funeral will be held for Michael on Tuesday morning in Los Angeles. Later that day, the public service will be held in downtown LA at the Staples Center.
No details were available on the location of the private funeral. However, several reports have suggested that Michael will be laid to rest at Forest Lawn Memorial Park in the Hollywood Hills.
