Justin Bieber will join Michael Jackson’s kids and the late King of Pop’s brothers for a celebration of the pop superstar’s life on Thursday Jan 26, 2012.

“Honoring the greatest @michaeljackson this week,” the pop star wrote on Monday in response to a message about the ceremony from Jackson’s Twitter account. “He set the bar for all of us. #MJFOREVER.”

Paris, Blanket, and Prince will use one of their late father’s sequined gloves and a pair of his shoes to make impressions in the cement outside Grauman’s Chinese Theatre on Hollywood Boulevard and the event, which will be streamed live via Twitter, will launch a day of Jackson celebrations.

Local schoolchildren will perform Jackson’s hits and the King of Pop’s brothers will also play live, according to reports.
