Ever since we found out that Mercedes and Santana were going to sing a diva-licious Adele mashup in the upcoming 'Mash Off' episode of 'Glee,' we've been impatiently waiting to see the real thing. Thankfully, the wait is over.

Fox has released the first sneak peek of the anticipated episode featuring Shelby's Troubletones take on the hyped-up Adele mash-up.

Honestly, after weeks of show tunes and older classics, we're happy to hear some Top 40 again. Not to mention that this might be one of our favorite 'Glee' tracks ... ever. Here's hoping that the Troubletones stick around for awhile because we need more of Mercedes and Santana's flawless duets.

And the best part? As our own Maggie Furlong previously reported, the mash-up is Adele-approved!
