Not lucky enough to have been in Las Vegas for Justin Timberlake's performance at the iHeartRadio Music Festival on September 21? We feel your pain — we weren't either. Luckily for us, though, videos from the concert seem to have magically found their way to YouTube. We've included the clips below.

JT rocked the stage with two new songs, performing "True Blood" and "Only When I Walk Away" from his new album, The 20/20 Experience 2 of 2, which is only four days away from its September 27 release date. (In case you're a little slow on the uptake today — we've got Monday brain, too, sister — that's the follow up to March's The 20/20 Experience.)

Mr. Jessica Biel joined a veritable who's who list of music stars: Katy Perry, J. Cole, Elton John, Drake, Paul McCartney, Muse, Tiesto, Chris Brown, Keith Urban, fun., Miguel, Bruno Mars, Phoenix, Zedd, Maroon 5, Tim McGraw, Thirty Seconds to Mars, Ke$ha, Benny Banassi, Queen, Adam Lambert, The Summer Set, Robin Thicke, and — of course — Miley Cyrus. (Now pardon us while we catch our breath.)

Between this, hyping his new thriller Runner Runner before it hits theaters on September 25, and receiving a butt mold from a Brazilian journalist, JT has been a busy man!
