The 2013 Video Music Awards are now only three days away, and it's safe to say we've lined up one of the most impressive performer lineups in VMA history: Lady Gaga, Kanye West, Miley Cyrus, Justin Timberlake, Robin Thicke and more. If we only had a glimpse at those rehearsals... Luckily, there are little things called Instagram and Twitter.

For the most part, our roster of VMA performers has been pretty hush-hush when it comes to sharing behind-the-scenes pics, but a few musicians have been getting decidedly snap-happy. Check out a few rehearsal pics from the likes of Miley Cyrus and Austin Mahone below.

Just Bein' Miley Backstage
Miley Cyrus is slated to perform on Sunday at the Video Music Awards, having been nominated for Best Song of the Summer, Best Pop Video and Best Female Video for "We Can't Stop."

Check out some of her decidedly silly backstage snaps below:

Nothing like a good Furry makeout sesh to get the creative juices flowing.

We hope she sports those slippers onstage.

Cyrus's signature hair gets a twist.

Austin Mahone Counts Down
Austin Mahone appears beyond pumped for his VMA pre-show appearance on Sunday — the Artist To Watch has been counting down the days. Publicly. On Instagram. Check out gleeful grams — and more — below.

Watch Mahone count to three!

He gets cryptic with this tweet. What looks insane, Austin? Care to share?

Pics or it didn't happen.

We Stand Here Waiting...
Lady Gaga is primed to open the 2013 Video Music Awards with the first-ever performance of her ARTPOP single "Applause," and we have no idea what to expect. Partly because Mother Monster has failed to live up to the promise tweeted below. Bang the gong already, Gaga!

Everything will be revealed when the show goes live from the Barclays Center at 9 p.m. ET/PT on Sunday, August 25.
