Last night, along with a long list of celebs, Justin Bieber attended J Lo's first residency concert in Las Vegas.
But, he had a little bit of an accident while he was leaving at the end of the show.
While he was trying to make his way through the crowds, he tripped and stumbled over a rather large suitcase.
He then proceeded to look very grumpy about it and picked up the suitcase, only to throw it on the seat in front of him. Ouch.
You sure don't like being embarrassed, Justin.
