The long-awaited Michael Jackson Tribute Concert takes place tonight, and already there’s major buzz about the show.

Jackson siblings LaToya, Tito, Marlon, and and Jackie Jackson were all smiles as they arrived in Cardiff, Wales yesterday, reports RadarOnline. Katherine Jackson and Michael’s three kids — Paris, Prince and Blanket — are all expected to be in attendance.

Fans who were expecting to watch the show via Facebook will be disappointed to learn that the livestream has been cancelled due to rights issues. Sales for the concert have also been so-so, with over 10,000 tickets still unsold for the event as of yesterday.

The concert has had its fair share of drama since it was announced back in August. Key performers Beyonce and Black Eyed Peas pulled out of the show recently.

But there’s still a great lineup to look forward to with Jamie Foxx scheduled to host and Christina Aguilera, Ne-Yo, Leona Lewis and Cee Lo Green all set to take the stage.

With all the shake-ups, do you think the show will be a big success?
