Cee Lo Green, Christina Aguilera to Lead Michael Jackson Concert Tribute [PHOTOS]

Grammy-winning recording artists Christina Aguilera and Cee Lo Green have agreed to perform for the king of pop's tribute concert titled "Michael Jackson Forever". The huge Michael Jackson tribute event on October will be featuring "Burlesque" actress-slash-singer, Aguilera, and the R&B superstar, Green, along with big names at the Millennium Stadium, a state-of-the-art stadium owned by the Welsh Rugby Union. "This announcement is just the beginning. This concert will (remind) everyone of just how amazing a talent Michael was," announce the organizers who already claim that the event will be "the biggest and best concert in the world."

Other huge artists that will perform on the event include Craig David, whose album "Born To Do It" made him an instant success in 2001, and British singing sensation Leona Lewis. Famous for making a remake of Jackson's "Smooth Criminal" as a single in, rock band Alien Ant Farm also agreed to perform for the tribute. British R&B boy band JLS is also preparing to perform, as well as Jackson's nephews 3T, whose songs frequently featured their famous uncle singing verses with the trio.

The Jackson Brothers are expected to be stars of the show, whose heartfelt grief and profound gratitude for Michael's music transcend with their performances. According to past reports, The Jackson Brothers have personally sent invitations to hit makers Justin Bieber, Usher, Bruno Mars and Chris Brown, but "respectfully declined" the offer. Entertainments site TMZ reports Kanye West is still thinking about joining the already exciting line-up of performers.

Although the event is due to happen in less than two months, tickets are still not on sale "The registration period was put on hold because we want people to know who they are registering to see." says Global Live Events chairman, Chris Hunt, who's looking over whole publicity of the tribute concert.. Described as a "donation-fueled" concert, fans are encouraged to bid high if they want to see the four-hour extravaganza in its entirety. Seats are expected to start at £55 for a restricted view, and fans are already fuming over the "bidding style" viewing.

"The higher you bid the better seats you get? Not every Michael fan is rich!!!" complains one fan in the event's Facebook page. Some fans are also saying that the organizers need to book more "exciting artists" other than Green, Lewis and Aguilera.
