Another Hollywood couple has called it quits.
Mary-Kate Olsen filed for divorce from husband Olivier Sarkozy after five years of marriage, ET confirmed Wednesday. While a source told ET the breakup is "brutal," things weren't always sour between the two.
Another source tells ET that the pair was always perceived as a bit mismatched by the public, but in reality they were a really well-suited couple who complemented one another -- and they were madly in love.
"He was always doting on her and making her happy," the source says. "And she loved being around him."
However, Olsen filed an emergency order to petition for divorce, claiming Sarkozy is trying to force her out of their New York City apartment, according to TMZ.
"Their relationship was a happy one and they truly seemed to enjoy each other’s company, which is why it’s all the more shocking to hear how contentious things sound right now," the source adds.
Olsen, 33, and the 50-year-old French banker have always maintained a private relationship. But as their separation unfolds, ET is taking a look back at the couple's love story, which started in 2012.
