They're fierce fashionistas and designers, but for their 29th birthday, Mary Kate Olsen
and Ashley Olsen
just wanted to have some good old-fashioned fun! The former Full House
stars celebrated the milestone by throwing the Olsen Olympics in the Hamptons. The day was filled with outdoor games and of course, friendly competition between the two twins.
Guests were assigned to Team Ashley or Team Mary Kate and given the appropriate team t shirt before participating in an obstacle course and dunk tank.
Team Ashley supposedly won the Olympics, but it looks like everyone had a blast. Twinning!
