he stars of the show, including AnnaLynne McCord, Michael Steger and Shenae Grimes, are currently filming their fifth and final series. It was recently announced that 90210 will come to an end on 13 May.
Prince Michael smiled and was relaxed on set as he was greeted warmly by the cast and crew members.
Before shooting the scene, he told Brooke Anderson of American showbiz news channelEntertainment Tonight that he prepared for his role by running his lines with his cousins, the director and his aunt.
It is the second time in the last fortnight that the teen has worked with Brooke. He received coaching sessions from her when he landed a job as a reporter for the channel.
His first assignment was to interview some of the cast and crew from the upcoming Disney film Oz the Great and Powerful, including director Sam Raimi and actors James Franco and Zach Braff.
The ambitious teen hopes director Peter Jackson will be his next interviewee. "I love his movies.Lord of the Rings, The Hobbit and King Kong. I just love the way he shoots.
"I used to study his movies with my dad, put the volume off and just watch it, just the shots to see how he put it together."
His new job will throw him into the spotlight that his late dad was so keen to protect his children from. Along with his two siblings, Paris, 14, and Blanket, 10, the trio had been kept out of the public view until Michael's memorial in 2009.
Since then, Prince Michael has been seen on a handful of occasions, often representing his father. Just months after he passed away in February 2010, the then 12-year-old accepted a Grammy Award for lifetime achievement on his behalf. The following autumn, he signed replicas of his dad's Beat It and Thriller leather jackets for a special amazon.com sale.
