What would have been M.J. 60th birthday?

Michael Jackson’s children, family members and friends came together to launch an auction, accept a posthumous award and remember the singer on what would have been his 60th birthday.

The “King of Pop,” children, Paris and Prince Jackson, brothers Tito and Jackie and R&B singer Usher joined some 1,500 guests in Las Vegas on Wednesday for a performance of the Cirque du Soleil show “One,” based on music by the “Thriller” singer.

Jackson died in Los Angeles in June 2009 after an accidental overdose of the powerful anesthetic propofol that he was using as a sleep aid. His personal doctor, Conrad Murray, served two years in prison for causing his death through negligence.

Prince Jackson along his sister Paris who is the ambassador of Elizabeth Taylor AIDS Foundation accepted the Legacy Award for their father.

“It is a privilege and honor to be here about something that my dad was so passionate about,” Prince Jackson said.

The siblings also launched an auction for a newly created pair of ruby and diamond-studded sneakers that are expected to fetch more than $50,000 at a November sale. The money will go to Taylor’s AIDS foundation.
