Paris, Blanket & Prince Jackson Plus The ‘Glee’ Guys Celebrate ‘Michael Jackson Immortal’ [PHOTOS]

If you are a serious Michael Jackson fan, Vegas is the new mecca. Hordes of the faithful flocked to Nevada this weekend for the first-ever estate-authorized fan festival coupled with Saturday’s opening night (December 3) of Cirque du Soleil’s blockbuster The Immortal.

The fan fest began Saturday and continues until at least Dec. 27, when the show hits the road for a 60-plus city tour that moonwalks into San Jose and Oakland in January.

The fan fest showcases some never-before-seen personal items including costumes, the Fantasy glove collection from the 1980s, award statues, tickets, the famed rocket plane from the “Leave Me Alone” video, a castle displayed in the living room of Neverland and much more.

Michael Jackson’s children Blanket, Paris and Prince were in attendance along with several other Jackson family members. A few Glee hunks were on hand as well – Mark Salling, Harry Shum Jr. and Kevin McHale were all on hand to represent!
