Ashley Tisdale (Sharpay) invited Lucas Grabeel (Ryan) onto her popular YouTube segment, "Music Sessions."
The duo reminisced about their days on the Disney franchise and tossed about a few fun memz.
"What's your favourite memory of me?" Ashley asks Lucas.
"Going on tour was such a monumental experience," Lucas replied.
"None of us had ever experienced anything like that before."
Ashley went on to gush about her former co-star and longtime friend, saying that "he can hit any note, he's the best singer out of all of us."
The pair then made all our hopes and dreams come true by singing a rendition of "What I've Been Looking For", the song that they sang together in the first flick.
