The much-anticipated Hannah Montana 20th Anniversary Special premiered on Disney+ this week, but fans quickly noticed a significant absence from the original cast lineup. Emily Osment, who portrayed Lilly Truscott, the best friend of Miley Cyrus's character Miley Stewart, was not featured in the nostalgic reunion special.
Filming Commitments Prevent Participation
Osment, now 34 years old, has provided a clear explanation for her non-appearance. In a heartfelt video shared on her Instagram account on Monday, the actress expressed her gratitude to the show's dedicated fanbase while revealing the practical reason behind her absence.
"We are at the Georgie & Mandy's First Marriage set, and that's why I was not able to be a part of the 20-year reunion, because we are here shooting our show," Osment explained in the video, which featured her alongside co-star Montana Jordan.
A Heartfelt Message to Fans
Despite her physical absence from the special, Osment made sure to connect with the Hannah Montana community. "I wanted to say hello and thank you to everybody that has stuck by us for all these years," she continued in her video message. "I'm so grateful that you guys all still love the show. I'm so proud to be a part of it... We appreciate you. Lots of love."
In the accompanying caption to her Instagram post, Osment elaborated on the profound impact the Disney series had on her life and career. "Hannah Montana changed my life," she wrote. "It gave me a lifelong respect for this medium of comedy, it taught me discipline, patience, timing and respect working in an adult space so young."
The actress expressed deep appreciation for the continued support from viewers, noting: "I can't tell you what your sweet messages mean to me and how lucky I feel to have been a part of this once in a generation goliath of a television show. Thank you for letting me into your living rooms and I hope to still be there many years from now."
Current Professional Endeavors
Osment currently stars as the titular Mandy McAllister in the CBS series Georgie & Mandy's First Marriage, which serves as a direct sequel to Young Sheldon within The Big Bang Theory franchise. Her commitment to this production schedule directly conflicted with the timing of the Hannah Montana anniversary special.
Another Notable Absence
Emily Osment was not the only original cast member missing from the reunion special. Mitchel Musso, who portrayed Oliver Oken (Lilly's boyfriend in the series), also did not appear in the anniversary celebration.
Musso shared his own reflective post on Instagram, writing: "Hannah Montana wrapped around my heart and never really let go. We literally grew up with ya'll — long days, crazy schedules, learning lines, cracking up between takes, and figuring out life while the cameras rolled."
While Musso did not explicitly state why he was absent from the special, his Disney career faced challenges following a 2013 DUI arrest. Despite this, he expressed profound gratitude to the cast, crew, and fans: "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. I'm honored we get to share all of this together."
Osment responded to Musso's post with a simple but affectionate comment: "Love you so so much."
Legacy and Availability
The Hannah Montana 20th Anniversary Special is currently available for streaming on Disney+, offering fans a nostalgic look back at the beloved series that launched the careers of multiple stars and captured the hearts of a generation of viewers.
While not all original cast members could participate due to various professional and personal commitments, the special serves as a testament to the enduring cultural impact of the Disney Channel phenomenon that originally aired from 2006 to 2011.
