The Michael Jackson Forever Tribute Concert kicked off Saturday to celebrate the life of the King of Pop.  Katherine, La Toya, Tito, Marlon and Jackie Jackson were in attendance as well as all three of Jackson’s children, Prince, Paris and Michael Joseph Jr. (Blanket).

Janet, Jermaine and Randy Jackson were absent because they were against holding the concert during the same time as Dr. Conrad Murray’s manslaughter trial.

Randy and Jermaine Tweeted: “While we wholeheartedly support the spirit of a tribute that honors our brother, we find it impossible to support an event that is due to take place during the criminal trial surrounding Michael’s death.”

The Black Eyed Peas dropped out last minute and Jennifer Hudson did not make it, but Ne-Yo, Jamie Foxx,  Leona Davis, Beyonce (via video), Christina Aguilera, and Cee Lo Green all performed. Fox sang MJ’s Billie Jean and Lady in My Life, Lewis performed Stranger in Moscow with ballerinas dancing in the background. Beyonce sang I Wanna Be Where You Are, via video.

Aguilera belted Smile and Dirty Diana and Green gave a soulful rendition of I Can’t Help it and You Can’t Win.

Also performing were Smokey Robinson, Alien Ant Farm, Craig Davis, Gladys Knight, Pixie Lott, 3T (Jackson’s nephews), Yolanda Adams and Alexandra Burke who all sang some of MJ’s biggest hits. Foxx joined SLS and The Jacksons to perform Rock With You and Don’t Stop ‘Til You Get Enough. Jackson’s children danced on stage during the show’s finale, Don’t Stop.
