And we're at such a loss of words, we're going to let Miz Teigen tell you what went down:
Liam Payne Breaks His Arm While Niall Horan Dances The Night Away! THIS Is How One Direction Does Vegas, Baby!
What ever happens in Vegas for the One Direction boys actually ends up all over the news!
LOLz! Ah, to be young and famous!
Luckily for the guys, Sin City was en route to their next tour stop in Arizona, so obviously the guys took a break and partied non-stop until they had to go back to work!
But it seems like Liam Payne went a little too wild because he was later spotted with a giant cast on his right arm at a private pool party above the Las Vegas strip!
The English cutie's right hand man (HA!) explained what exactly went down on Twitter, saying:
Meanwhile, Niall definitely had a great outing with the group's famed hair stylist, Lou Teasdale and even bumped into Joe Jonas inside the loo!
What a semi-awkward encounter that might've been!
Needless to say, the guys survived their first outing in Sin City!
