Lea Michele and Ashley Tisdale have teamed up to give fans a taste of "Glee" and "High School Musical" crossover. The two joined forces to cover Robyn's hit single "Dancing on My Own" on Ashley's popular YouTube series, "Music Sessions", and it could give you chills as it was a pure perfection.

"Every single time I've come out with a new Music Session, you think it's her, so here she is," the former Disney star said before introducing Lea. "Thank you so much for being here. I mean, if I didn't have a husband [Christopher French] I'd marry Lea so... I just love you so much."

After chatting about Lea's new album "Places" and their mutual interest in medication classes, the pair belted out a dreamy acoustic rendition of the song. They perfectly turned the original dancey track into more slow-beat version while combining their smooth vocals, with Ashley's husband Chris on the guitar.

Since creating "Music Sessions", Ashley has dueted with a number of stars. Earlier this year, she invited "HSM" co-star Vanessa Hudgens to sing "Exes and Ohs" together. She has also invited Debby Ryan to cover Destiny's Child's "Say My Name". In May, Ashley reunited with Lucas Grabeel to do a collaboration of "HSM" classic, "What I've Been Looking For".
