Watch Teenagers and Grown Women Alike Lose Their Sh*t Over Justin Bieber's Latest Surprise

During the final day of "Bieber Week" on The Ellen DeGeneres Show on Friday, Justin Bieber made a special announcement during his outdoor concert. After giving an amazing performance of his new song "Sorry," the singer gave all 4,000 people in the audience tickets to An Evening With Justin Bieber at the Staples Center in LA. Everyone understandably freaked out, producing screams that will probably echo in your ears for days. But the most hilarious detail about the moment was, in addition to teenagers losing their minds, you can clearly see grown women in the crowd also jumping up and down.

Justin's gesture is just the latest thing he's done for his fans this week. After surprising four lucky girls with concert tickets, he pranked Ellen's audience members by dressing up as a security guard. Watch the latest moment above, then check out what happened when he met Diane Keaton.
