Nine years after the third High School Musical film hit theaters, Sharpay and Ryan Evans are back and showing us that their duet skills and plans for musical domination are far from rusty.

The Evans twins, aka Disney alums Ashley Tisdale and Lucas Grabeel, proved that their Wildcat days are far from over as they reunited for a special performance of their 2006 duet track "What I've Been Looking For" from the first film, and the nostalgia-filled singing session is giving us all the feels.

Taking to Instagram on Tuesday, the actress teased the very special YouTube collaboration with Grabeel, who plays her brother in the popular film trilogy.

"You asked for him! New Music Session with @mrgrabeel!! This one is so special to me and we did it just for you guys. Link in bio to find out what song we did..... you don't want to miss this!" she wrote alongside a still of the pair recording together and somehow managing to look like they haven't aged a day from their HSM days.

In the YouTube video, we see the co-stars reminiscing about their Wildcat days, with the actor telling the star, "It's been 10 years since we sang this song so it was really crazy just thinking what would be the best song to sing with you and this instantly came to mind. All of these memories came coming back."

While the Sharpay's Fabulous Adventure lead was quick to heap the praises on her on-screen brother, gushing, "His voice, he can hit any note. He's just the best singer out of all of us. It's insane how good of a singer is," she also admitted that the pair hadn't always been good friends.

"We were not close. We were not big friends. We hated each other," she revealed of the duo's relationship during the series, chuckling. "After we wrapped, I always had a love for you."

This isn't the first time Tisdale has invited a High School Musical alum to join her for a singing collaboration on her channel. Vanessa Hudgens—who played Gabriella Montez, love interest to Zac Efron's character Troy Bolton in the series—joined in for a cover of Elle King's hit single "Ex's & Oh's" to ring in the new year.

Could Efron be next in bringing his musical chops to Ashley's channel? We're crossing our fingers!

Watch Tisdale and Grabeel reminisce about their Wildcat days and take us down memory lane with a performance of "What I've Been Looking For" in the video above.
