Prince Michael Jackson to Guest Star on 90210

Prince Michael Jackson is set to make his acting debut on 90210.

Michael Jackson's eldest son will guest star on the Season 5 finale as Cooper, a trauma victim Silver bonds with as they both realize how precious life is.

Sounds like pretty deep stuff right there.

The 90210 gig comes a week after Prince, 16, joined ET as a correspondent for the celebrity news program. He's moving and shaking, that Prince!

In other Jackson family news ... his aunt dropped a major bombshell in a statement Monday. Janet Jackson and Wissam Al Mana apparently got married!
