Beyonce Knowles is set to perform at the upcoming Michael Jackson tribute concert, but not in person -- rather, via satellite.

The Halo singer was a huge a fan of the Thriller hit maker, who passed away from acute Propofol intoxication in June 2009 at the age of 50. Now, it’s been confirmed she will take part in the Michael Forever Tribute Concert, which is due to take place at the Millennium Stadium in Cardiff, Wales, on October 8.

However, she won't be able to make it in person because of "scheduling issues," but has found a way to be involved.

The Jackson family is at war over the Michael Forever Tribute Concert, and a major contributing factor is Katherine Jackson's decision to have Michael's three children attend the event, RadarOnline.com is exclusively reporting.

The concert is scheduled to take place in Wales, Great Britain on October 8, 2011.

Michael’s brothers Jermaine and Randy are also upset about the timing of the concert, because Dr. Conrad Murray's involuntary manslaughter trial will be going on at the same time.
