Michael Jackson's family will attend the world premiere of a new documentary exploring the life of the singer.

Katherine Jackson and her children Tito and Rebbie will join David Gest for a special screening of 'Michael Jackson: The Life Of An Icon' - which comprises interviews with more than 50 of Michael's closest friends and family - at the star-studded event at the Empire, Leicester Square, in London next month.

David will also host a special after-party which will feature performances from several soul legends who appear in the film and he will also present Tito and his new fiancee Sonia Galineo with a special gift to mark their recent engagement.

David said: "I am thrilled that Katherine, Tito, Rebbie, director Andrew Eastel, Thomas [Mesereau] and Susan [Yu] as well as 100 stars will be in attendance for the world premiere of my new film. There is going to be a Jam at the invitation-only after-party following the premiere and more than 20 legendary artists who appear in the film will take part. This party is going to be historic!"

Katherine, Tito, Rebbie, Andrew, David and lawyers Thomas Mesereau and Susan Yu - who successfully acquitted Michael of all charges during his child molestation court case in 2005 - will also participate in a special Q&A to discuss their involvement in the project prior to the screening.

Jackson 5 star Tito popped the question to fitness and beauty expert Sonia - who he has been dating for years - in August and she didn't hesitate to say "yes".

David hosted a party at the Bellagio Hotel in Las Vegas last month for Tito and Sonia which was also attended by other members of the Jackson family including his brother Jackie and mother Katherine.

During the bash, David was mobbed by 40 English people dining at a nearby table who were asking him about his time on 'I'm a celebrity. Get Me Out of Here!' in 2006 and his housekeeper Vaginica Seaman, who he spoke about in the jungle and whom Michael knew.

Katherine, 81, asked the producer: "Is that her real name?"

To which he replied: "Yes."

Katherine then exclaimed: "She should change it!"

The 58-year-old star also wanted to thrown the bash to lift the family's spirits ahead of the start of the involuntary manslaughter trial of Dr. Conrad Murray - who is accused of administering the lethal dose of Propofol which killed Michael in June 2009.

'Michael Jackson: The Life Of An Icon' will hold its world premiere at the Empire in London's Leicester Square on November 2.
