The duo introduced a performance from "MJ the Musical" -- the Broadway show all about the making of Jackson's 1992 Dangerous World Tour.
Prince told the audience, "A lot of people seem to think our dad Michael Jackson changed popular music forever,' before adding: 'And, who are we to disagree?"
"But, what people may not know is he loved musicals, on film and on the stage. That's why we are so incredibly honored to introduce the night's first nominee for best musical, 'MJ', which, using many of his iconic hits, looks at the complexities and brilliance of our father's process."
Paris added, it was a great honor to be on stage introducing the musical performance, along with actor Myles Frost, who plays their dad ... and the rest of the cast. The show was nominated for 10 Tony Awards, including Best Musical.
Myles seemed to do their dad's role justice cause he also won Best Performance by an Actor in a Leading Role -- his first Tony ever!
