Move over, Jimmy Fallon: You're not the only NBC television personality having a public bromance with Justin Timberlake -- and Matt Lauer is trying to one-up you by making it official!

The TV host made the most of the pop star's appearance on the 'Today' show this morning (Sept. 19), turning a normal Q&A into a crazy segment featuring the pair re-enacting a scene from 'The Hangover' and even getting hitched to each other!

Lauer jetted out to Vegas to chat with JT, covering topics like next flick 'Runner Runner' and upcoming album 'The 20/20 Experience - 2 of 2.' Justin even once again comes to the defense of fellow Disney superstar Miley Cyrus.

All standard interview stuff. But the clip gets surreal when they take advantage of their Sin City locale to parody the "satchel" bit from buddy movie 'The Hangover,' with Justin hilariously taking over the Zach Galifianakis role. Then JT and Matt -- who have a history together, publicly playing mind games on each other a couple of years ago -- get married in a Las Vegas wedding chapel, with an Elvis impersonator presiding. Watch the crazy clip above, and be sure not to miss Justin pinch Matt's butt at the end!

Expect more bromance wackiness when another JT segment airs on 'Today' early next week. Guess it's your move now, Jimmy!
