Reese Witherspoon Is Dating Private-Equity Financier Oliver Haarmann: Sources (Exclusive)

The relationship is "just casual," says a source of the couple, who stepped out for a date night on Wednesday, Sept. 4

Reese Witherspoon and Oliver Haarmann have taken their relationship to the next level.

Multiple sources confirm exclusively to PEOPLE that the pair have moved from friends to dating after they were spotted on Wednesday, Sept. 4, in New York City together for at least the second time in little over a month, this time for an Assouline opening event that also included Roger Federer and Anna Wintour.

Financier Haarmann was dressed in khaki-colored pants and a dark-colored belt matching his shoes, with a tucked-in light-blue button-up shirt under a darker-blue blazer.

The Oscar-winning actress rocked a short-sleeved black dress and matching strappy heels as they walked together, holding a black coat in her left hand.

"They’re friends and it’s just casual," an insider says of the pair's romance.

A rep for Witherspoon has not commented to PEOPLE.

The two arrived via helicopter on July 29 and dined at L'Artusi in the West Village neighborhood the following day.

A source told PEOPLE at the time that Witherspoon and Haarmann were "friends," while another insider said the Legally Blonde actress was "taking things slow when it comes to dating."

"She enjoys it but doesn't want it to be a big focus. She's busy with work and her son," says the insider. "These are her biggest priorities."

Witherspoon and ex-husband Jim Toth announced their divorce in March 2023, after nearly 12 years of marriage. The former couple share one child, 11-year-old son Tennessee. They had settled their divorce by August 2023.

The Hello Sunshine founder also shares two kids with her first husband, fellow actor Ryan Phillippe: daughter Ava, 24, and son Deacon, 20.

Witherspoon previously opened up about how her divorce from Toth, 54, compared to her 2006 split from Phillippe, 49, while speaking with Harper's BAZAAR for the magazine's August 2023 issue.

"To be able to talk to people directly about what’s going on in my life and just share it in the way that I share great professional experiences or personal experiences," she said, "it feels much more authentic to be able to say things in my own voice and not let somebody else control what’s happening."

Added Witherspoon, "Then, of course, there’s speculation, but I can’t control that. All I can do is be my most honest, forthright self and be vulnerable."
