Miley Cyrus has joked she's too "tired" for a full Hannah Montana reboot.

The 33-year-old former child star rose to fame as the titular character in the hit Disney sitcom between 2006 and 2011, and while she has filmed a 20th anniversary special to mark two decades since the first episode aired, she hinted that actually bringing back the show would be a step too far.

Asked about a potential reboot on the red carpet of the Disney+ special's premiere, she told Variety: "Girl, I'm already tired! This has already been a lot."

The beloved sitcom starred Miley as teenager Miley Stewart, who lives a double life as a famous pop star.

In the special, Miley sings some of the show's most popular songs, as well as sitting down for an interview with Call Me Daddy podcast host Alex Cooper.

There will also be a surprise appearance from Selena Gomez, who played Hannah's pop star rival Mikayla Skeech in season two, plus never-before-seen archival footage.

Miley was joined by her fiancé Maxx Morando, 27, for the premiere at the El Capitan Theatre in Hollywood, as well as sister Brandi, 38, and her mother Tish, 58, who attended with her husband Dominic Purcell, 56.

Dad Billy Ray, who starred in the sitcom and will appear in the special, wasn't at the premiere, while former co-star Emily Osment was also missing.

The 34-year-old actress - who played Miley's best friend Lilly Truscott - has confirmed she didn't take part in filming for the anniversary show due to filming commitments for her series George and Mandy's First Marriage.

She said in an Instagram video: "I wanted to say hello and thank you to everybody that has stuck by us for all these years.

"So grateful that you guys all still love this show. I'm so proud to be a part of it."

She added in the caption: "Hannah Montana changed my life, 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.

"I can't tell you what your sweet messages mean to me and how lucky I feel to have been apart 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."
