Miley Cyrus is still feeling nostalgic for her Disney Channel days.

Last night (Apr. 2), the Disney alum threw it all the way back to the early-'00s when she uploaded a string of videos of her singing along to a classic from fellow Disney queen Hilary Duff as well as a few show tunes from High School Musical.

In the first vid, Cyrus, dressed in a proper Mickey Mouse T-shirt while enjoying her solo karaoke session in the view of a moving vehicle, can be seen belting out the words to Duff's iconic 2003 jam "So Yesterday." The "Nothing Breaks Like a Heart" singer continued to turn up the nostalgia in the two snippets that followed, in which she sings "Breaking Free" from HSM and "Stick to the Status Quo" from its sequel, High School Musical 2.

"This shaped a f**king generation," Cyrus writes in the caption of the first clip, tagging the record's original performers, Zac Efron and Vanessa Hudgens. "I’m glad in 2019 we’re challenging this garbage," the 26-year-old quips in the clip, along with the hashtag "#NoQuo."

Cyrus' latest musical trip down memory lane to her days on Disney should come as no surprise. Although it's been more than 13 years since the "Malibu" artist last performed as the titular teen superstar on Disney Channel's Hannah Montana, Cyrus gave Smilers something to smile about last week when she brought back Hannah's iconic blonde wig on social media.
