Do You Know Why One Direction & 5SOS Are Wearing Big Red Noses?

If you don't know about Red Nose Day yet, it's time to get informed! The event has been around since 1988 in the U.K., but on May 21 you can tune into the first-ever U.S. Red Nose Day, featuring people we all love including One Direction, Ed Sheeran and 5 Seconds Of Summer. Here's why you need to watch!

One Direction are performing, and as Red Nose Day veterans they know what they're doing. Remember their version of "One Way Or Another"? It was the official Red Nose Day single if 2013.

Of course, Uncle Simon will also be crossing the pond to join 1D's U.S. Red Nose Day debut

Ed Sheeran will be teaming up with Kermit for a very special song… We're hoping for "Rainbow Connection" or "Thinking Out Loud"

Any time 5SOS are on our TVs is cause for celebration.

Chris Pratt is Star-Lord, Emmet from The Lego Movie AND a dino wrangler in the upcoming Jurassic Park sequel. What's not to love?

Zendaya is our queen, and the fact she's not afraid to get a little silly for Red Nose Day makes us love her even more.

Our favorite Voice judge Blake Shelton is also joining in to make a HUGE difference.

Watch the show on NBC on May 21st at 8/7c to catch it all, and be sure to donate what you can to help lift young people out of poverty in the U.S. and the rest of the world!  Buy a Red Nose from Walgreens or Duane Read for $1, and 50¢ will go to the Red Nose Day Fund.
