The 22-year-old, whose real name is Michael Joseph Jackson, Jr., took to social media to share a photo from a group outing to see the record-breaking new Marvel film, "Avengers: Endgame," which included a bunch of friends and his younger brother, now 17. Sister, Paris, is not in the shot.

Blanket, whose real name is Prince Michael Jackson II, started going by Bigi back in 2015 after enduring years of bullying because of his name. He's kept largely out of the public eye since 2012, when he stopped making appearances at public events in the years after his father's death in 2009, and sources told People that he's "had the most problems adjusting after Michael died."

"He acted very lost and extremely upset," one source said, though he's now "confident" in his environment -- though he's still "shy around people he doesn't know."

Prince and Paris, however, haven't been shy about hitting red carpets and leaning into celebrity culture in recent years.

Blanket's unexpected appearance on Prince's Instagram comes amid continued press around the HBO documentary, "Leaving Neverland," detailing allegations made by Wade Robson and James Safechuck claiming that Jackson sexually molested them as children. While Prince and Blanket have never publicly commented on the film, Paris has tweeted several times about it and expressed her desire to largely stay out of the conversation.
