This month the greatest show on Earth is coming to Britain - no, not the Justin Bieber tour, but the Olympic Games!
Billions around the world will tune in for the opening ceremony at the Olympic Stadium on Friday 27 July.
Oscar-winning director Danny Boyle is in charge. He's giving the show a countryside theme!
Across the country, loads of people will be celebrating the start of the biggest sporting event in UK history.
On 27 July, CBBC will be live from Middlesbrough for the Olympic Games Challenge.
Kids there are planning and organising a massive event for their town - their preparations will be shown on CBBC in the week leading up to it.
What are YOU doing for the opening ceremony?
Perhaps you're throwing an Olympic party with your mates or at your school? You could go red, white and blue, or all be different countries!
Are you dressing up as your fave sporting heroes? It's your chance to be Usain Bolt or Jessica Ennis!
Maybe try your hand at cooking some Olympic-themed food? Javelin chips, anyone?
Whatever you're up to, we want to know...
