Jackson began his new job Monday. One of his first assignments was to interview the stars of the upcoming family film "Oz the Great and Powerful."
"ET" correspondent Brooke Anderson welcomed Jackson to the show via Twitter, saying the teen "rocks" and is "impressive."
TVGuide.com noted Jackson had a link to the film he was covering since his father starred in the 1978 movie musical, "The Wiz," which was an adaptation of the 1939 classic "The Wizard of Oz."
Michael Jackson died in 2009 of an overdose of anesthesia and sedatives while trying to battle insomnia. He was 50.
The Grammy Award-winning recording artist is survived by his three children -- Prince Michael; daughter Paris, 14; and son Prince Michael II, also known as Blanket, 11.
