Mary-Kate Olsen & Businessman John Cooper 'Seem Like A Great Match,' She Hasn't Been This Happy In 'Many Months' Says Source

Mary-Kate Olsen is moving on! One month after finalizing her divorce from Olivier Sarkozy, 51, the Full House alum has started a new romance with businessman John Cooper, a source tells OK!.

"They met through mutual friends and have been enjoying each other's company. They seem like a great match," the source says of Olsen and Cooper, who were spied out to dinner in NYC on February 26 at one of the 34-year-old designer's favorite Greek eateries, Estiatorio Milos. 

The two first came face-to-face in January at a virtual hearing, where it was revealed that Olsen and Sarkozy had reached an agreement in their divorce.

"No one in her circle has seen Mary-Kate this happy in many, many months, and they owe it to John," says the insider. 

According to the source, Cooper, 45, is very much Olsen's type. "He's a self-starter, an Ivy League grad, a CEO of his own tech company and he isn't impressed with fame or the limelight, which is very important to an ultra-private person like Mary-Kate," spills the source. "He's also a licensed pilot and he knows his way around the kitchen, having gone to the French Culinary Institute." 

And while Cooper's never been married, "that isn't a red flag for Mary-Kate," adds the source. "She finds him absolutely charming." And even though their budding relationship is still fairly casual, the fashion icon is "definitely open to something serious," notes the source.

For the first time in a while, "Mary- Kate's feeling positive about the future and good about herself — and John is helping her unwind and have fun."

As previously reported, Olsen decided to end things with Sarkozy when he invited his ex-wife, Charlotte Bernard, to move into their $5 million Bridgehampton, N.Y., mansion. "Olivier was concerned for the safety of his family in New York during the pandemic. He insisted to Mary-Kate that he wanted to bring his ex-wife, their kids, and his mother from the city to their Bridgehampton home," a source had told Page Six at the time.
