Last week's episode of 'Glee' marked the anticipated return of The Warblers -- and the preppy jackets, those blue and red striped ties and all that adorable sidestepping.

In a newly released video, Fox takes us behind the scenes with Darren Criss as he returns to Dalton Academy and performs 'Uptown Girl' with The Warblers. Fangirls, be ready because Criss is really going to melt your hearts in this one.

"It's just so much fun to be a Warbler," Criss says. "I think everybody at some point in their life should be a Warbler."

You can sign us up any day. Gleeks, watch the super cute Warbler video after the jump.

Darren Criss and his Warblers better watch their backs! With 'Glee' on hiatus for the summer this little boy is filling the void with his spot-on impressions of the Dalton Academy singing group that captured hearts this season. The tiny Warbler has it all down -- the singing, the moves and and even the costume! He's just a little too young to be anyone's Teenage Dream yet.

The 'Glee' cast, complete with members of the Warblers, is on tour this summer performing hits from the series. Check out the mini Warbler's moves and tell us what you think!

The Warblers used to be a fictional a cappella group from 'Glee.' They are a little closer to being a real group, with an appearance on 'Today' (weekdays, 7AM on NBC) and a new album, 'Glee: The Music Presents the Warblers.' On the show, the Warblers are given voice by an a cappella group called The Beelzebubs, the Tufts University troupe who also competed on 'The Sing-Off.' Actors Chris Colfer and Darren Criss handle their own leads.

It was the actors from the show backing Criss on the 'Today' appearance, on which the Warblers sang the Train hit 'Hey, Soul Sister.' The Warblers' version of Katy Perry's 'Teenage Dream' hit reached no. 1 on the Billboard charts with Criss singing, something he still has a hard time believing. "It just happened so quickly and we've all been so thrilled that there's been such a positive reception," said Criss.

Criss said the 'Glee' schedule keeps him pretty busy, and he hasn't had time to think about a solo album yet. He said it certainly isn't out of the question, and it's a safe bet the opportunity will present itself.
