Michael Jackson's youngest son - formerly known as Blanket - is all grown up and completely unrecognizable. In a touching tribute to their legendary father, Bigi (FKA Blanket), 21, and Prince, 26, stepped out in Las Vegas to celebrate what would have been Michael's 65th birthday. The siblings made their rare appearance at the famed Mandalay Bay Resort and Casino, the same venue that hosts the spectacular Michael Jackson ONE show by Cirque du Soleil. And the now not-so-little one - who was watched by millions of people around the world as he and his siblings said their goodbyes to their famous dad at his televised memorial 14 years ago - is all grown up. The brothers were there to interact with fans of the late King of Pop. One devoted fan even presented them with a photo of Michael, which also featured an angel. [[twitterwidget||https://twitter.com/etnow/status/1696877332538274221]] Cirque du Soleil's website announced that the event was far from an ordinary one. Named the "Blue Sapphire Birthday Celebration," the evening featured a public Q&A session hosted by members of Michael's estate. Fans also looked forward to a spellbinding performance by the cast of the Las Vegas show, promising to be "part music, part acrobatics, and all amazing," as previously described. The celebration doesn't stop there; Michael Bush, author of The King of Style: Dressing Michael Jackson, will be present for a book signing. And for those who can't get enough, a meet-and-greet with the original creative team behind Michael Jackson ONE and representatives from the Grammy winner's estate is also on the itinerary. To sweeten the deal, attendees with proof of ticket purchase will be treated to complimentary cake and cupcakes. First unveiled in February 2013, the Michael Jackson ONE show marks its 10th-anniversary residency in Vegas this year. "Everything [Jackson] does is with a childlike heart. For Michael, every day was fresh, every day was new, every day had to be bigger and better than the last one," shared Michael's friend and choreographer, Jamie King, via <a href="https://people.com/blanket-jackson-makes-rare-appearance-on-what-would-have-been-michael-jackson-s-65th-birthday-7963511?utm_campaign=peoplemagazine&utm_content=manual&utm_medium=social&utm_source=facebook.com&utm_term=64eea04f6a64f500015e855f&fbclid=IwAR2wG_7lMKzE6zSQdbPDiaSNLrdtR5GS6S7zkeX_OemXjCHFBYa3LbtefTI">PEOPLE</a>. This emotional tribute isn't an isolated event. The Jackson kids have honored their father's towering legacy before. In August 2018, Paris and Prince attended the "Michael Jackson Diamond Birthday Celebration" at Mandalay Bay. They received the Elizabeth Taylor Legacy Award on their father’s behalf for his humanitarian work, notably with the Elizabeth Taylor AIDS Foundation. Elizabeth Taylor, a long-time friend of Michael, was also Paris' godmother. "He supported Elizabeth and the cause with his time, celebrity, and donations," Paris noted. In a past PEOPLE interview, a former bodyguard for the 'Man in the Mirror' singer described Michael's children as "well-mannered, well-behaved kids." Michael’s publicist reinforced the sentiment, emphasizing that the children "were Michael's first priority." Paris, who was just 11 at the time of Michael's 2009 funeral, summarized the collective feelings best: "Ever since I was born, Daddy has been the best father you could ever imagine. And I just want to say that I love him so much." As Michael's 65th birthday rolls around, the legacy of the pop icon lives on not just in his music and humanitarian work, but also in the family that continues to honor him. <h6>Featured image credit: Pool / Getty</h6>
