It's going to be far from a Full House for Mary-Kate Olsen and boyfriend Olivier Sarkozy when they stay at the extravagant Manhattan townhouse that he recently bought.

MK's older man has reportedly paid $6.25 million for the East 10th Street, which just like his 26-year-old girlfriend – has a twin!

According to the New York Post, the 42-year-old brother of the former French president bought the historical home and reportedly plans to share it with his former child star girlfriend.

As Breaking Celebrity News previously reported, the couple began their surprise relationship in May and petite Mary-Kate was first seen spotted snuggling with the French asset manager a month later at a New York Knicks basketball game.

Having previously dated actress Stella Schnabel, Olivier has also been married before and has two children. Blonde fashionista Olsen was with New York artist Nate Lowman between 2008 and 2010, and also dated Greek shipping heir Stavros Niarchos.
