You might think that the Olympic Games are busy enough with all the different sports that take place.
But it's been decided that two new sports are going to be squeezed into the 2016 Olympics in Brazil.
Golf and rugby sevens have been given the go ahead by the bosses of the Games, the International Olympic Commission.
They agreed to the new sports back in August but the decision to include them became official on Friday.
Rugby sevens is a form of rugby with seven players instead of the usual 15 and shorter matches.
Sporting stars from the worlds of golf and rugby, including Jonah Lomu and Tiger Woods backed their events becoming part of the Games.
New events are often added to each Olympics Games. Women's boxing will be included for the first time at the 2012 games in London.
