Katy Perry's "Teenage Dream” was featured on Glee Tuesday night in a fantastic performance starring newcomer Darren Criss, and the pop star was ready to cry with joy when she saw it.

The newlywed singer took to Twitter to express her Glee over the moment: “'Oh...My...Gosh... this just brought a sweet tear to my eye! Teenage Dream on GLEE makes my heart go WEEEEE!”

We know just how you feel, Katy. Check out the video above to see the entire performance. The goofy smile on Chris Colfer’s face sums up our feelings perfectly.
