BACK TO SLIDE
Move aside, Super Bowl commercials -- we're envisioning an epic Full House reunion is on the horizon! According to Us Weekly, Mary-Kate Olsen is engaged to Olivier Sarkozy, and will soon become a stepmother! Mary-Kate, 27, and Olivier, 44, currently live together in a $6 million townhouse in New York City.
The couple started dating in 2012 and are frequently spotted together at Knicks games in Madison Square Garden. We can't wait to see Mary-Kate's wedding gown -- and of course the bridesmaids dresses! Ashley will most likely be Maid of Honor, right..? And their (equally chic) sister Elizabeth is bound to be a bridesmaid.
We're betting on Mary-Kate and Ashley collaborating on a unique dress just for the bride-to-be. A major perk of being a fashion designer, don't you think?
This is Mary-Kate's first marriage and Olivier's second -- his two children from his previous marriage are aged 10 and 12.
