Hannah Montana 20th Anniversary Special Premieres Without Key Original Cast Members
The highly anticipated Hannah Montana 20th Anniversary Special debuted on Disney+ on March 24th, 2026, delivering an iconic celebration that fans had eagerly awaited. The special featured Miley Cyrus performing classic hits like 'The Best of Both Worlds' and 'The Climb' in full Hannah Montana attire, alongside guest appearances from stars such as Selena Gomez and Chappell Roan.
Notable Absences Spark Fan Confusion
However, viewers were left puzzled by the absence of two original cast members: Emily Osment, who played Lilly Truscott, and Mitchel Musso, who portrayed Oliver Oken. Neither actor appeared in the pre-recorded special nor attended the red carpet premiere event, where other beloved co-stars like Jason Earles (Jackson) and Moisés Arias (Rico) reunited with Miley Cyrus.
This omission raised questions among the show's dedicated fanbase, leading to speculation about why these foundational characters were missing from such a significant milestone celebration.
Emily Osment's Filming Commitments Explained
Emily Osment has publicly addressed her absence from the premiere through social media. In an Instagram video, she explained that she was unable to attend the Los Angeles event due to her filming schedule for the second season of Georgie & Mandy's First Marriage, a spinoff of The Big Bang Theory.
"We're at the Georgie & Mandy set, and that's why I was not able to be a part of the 20-year reunion," Osment stated. She expressed gratitude to fans, adding, "I wanted to say hello and thank you to everybody that has stuck by us for all these years. I'm so grateful that you guys all still love this show. I'm so proud to be a part of it."
In her caption, she further emphasized her appreciation: "Would never be where I am without you guys, working on another beautiful show I love so dearly. With all my heart, THANK YOU!" It is possible that Osment's filming commitments also coincided with the taping of the anniversary special, preventing her participation entirely.
Mitchel Musso's Unexplained Absence and Speculation
In contrast, Mitchel Musso has not provided a clear explanation for his absence from both the special and the premiere. This has led to fan theories, particularly in light of his legal issues in 2023, when he was arrested for charges including public intoxication, theft under $100, expired registration, failure to display a driver's license, and violating a promise to appear notice.
Although these charges were dismissed later that year, some fans speculate a connection to Disney's decision to recast his character Jeremy in the 2025 revival of Phineas and Ferb. Disney has never officially commented on the recasting, and Musso has remained silent on the matter as well.
Despite his absence, Musso took to Instagram to mark the anniversary, posting: "To all of you, thank you for welcoming me into your homes and hearts 20 years ago and still allowing me to be here today."
Miley Cyrus Acknowledges Former Co-Stars
During the special, Miley Cyrus did reference both Osment and Musso, sharing personal anecdotes with host Alex Cooper. She revealed that she had a crush on Musso when they first began working together and described Osment as feeling like a teammate, highlighting the enduring bonds formed during the show's original run.
The Hannah Montana 20th Anniversary Special serves as a nostalgic tribute to the series that defined a generation, even as it moves forward without all of its original stars. Fans continue to celebrate the legacy of the show while pondering the reasons behind these notable absences.
