Michael Jackson's Son, Prince Jackson, Graduates From High School

— -- Prince Jackson would make his father proud.

The oldest child of the late pop star Michael Jackson, he graduated from high school Saturday -- with honors.

Prince Jackson's aunt, La Toya Jackson, tweeted a photo of the two of them at the graduation ceremony at the private Buckley School in Sherman Oaks, California, writing, "So very proud of @princemjjjaxon," she wrote. "YOU DID! And you did it with Honors!!! #buckleyclassof2015."

Cousin Tito "TJ" Jackson, 36, who was made a co-guardian of Michael's children in 2012, also posted a photo of him posing with the 18-year-old graduate and his diploma at the ceremony.

"Prince, you have grown into an incredibly special young man," he wrote. "Words can’t express how proud I am of you. I will ALWAYS be here to support you wherever life takes you. I love you!"

Prince's 17-year-old sister Paris Jackson was also spotted by Us Weekly giving her big brother a hug.

It hasn't been easy for Jackson's three kids, including 13-year-old Blanket Jackson, since their father died in June 2009.

They moved in with the singer's mother, Katherine Jackson, now 85, but she temporarily lost guardianship amid a bitter family dispute over Michael Jackson's estate in 2012. A judge then made TJ Jackson, the son of Michael's brother Tito Jackson, a permanent co-guardian along with Katherine.

Though homeschooled when their father was alive, the two oldest children began attending Buckley school soon after moving into Katherine's suburban Los Angeles home.

It's the same school that their famous dad and other members of the Jackson clan attended.

At the time, family attorney Brian Oxman described Prince to ABC News as "a very powerful personality" who wanted to be around kids his own age.

"I get the sense that Prince really likes business. And he likes speaking," he said in 2010.

Prince, who has had a guest role on the CW's "90210" and been a special correspondent for "Entertainment Tonight," told "ET" correspondent Brooke Anderson in 2013, "I'm looking to become well-rounded as a producer, director, screenwriter and actor."
