It was quite literally all fun and games at Mary-Kate and Ashley Olsen's birthday bash this weekend as the twins hosted the Olsen Olympics in celebration of their 29th birthday.
Guests were divided into two teams - with the red team representing Mary-Kate and the blue representing Ashley - before being invited to take part in an outdoor competition. Activities included dunk tanks, obstacle courses and a colourful maze - far more fun than your typical glitzy soiree, if you ask us!
The 2015 CFDA Womenswear Designer of the Year winners went head-to-head throughout the day before Team Ashley were crowned victorious and celebrated with sparklers and fireworks.
Mary Kate and Ashley might not have Instagram, but that didn't stop pictures ending up on our feed.
We aren't normally ones to take part in sporting events but we'd certainly make an exception for the Olsen Olympics!
