Reese Witherspoon’s romance with businessman Oliver Haarmann is heating up.

The “Morning Show” star, 49, and German financier, 57, were snapped by paparazzi over the weekend while vacationing in St. Tropez, France, together.

Witherspoon and Haarmann were aboard a yacht at the time, and could not resist a steamy makeout.

In one of the images, the “Legally Blonde” star — who was photographed wearing only a white one-piece swimsuit — had her arms wrapped around her beau, as she leaned in for a passionate kiss.

He also appeared just as lovey-dovey, leaning forward to give Witherspoon a smooch in another shot.

The couple took a brief break from their public display of affection to go for a dip in the water to snorkel.

However, while in the Mediterranean Sea, the lovers were once again back to locking lips. They then continued their PDA-fest after putting on some T-shirts and going back onto their yacht.

Witherspoon and Haarmann were first romantically linked in July 2024, but a source told People at the time that the “Big Little Lies” alum was “taking things slow” with her new man.

“She enjoys it but doesn’t want it to be a big focus. She’s busy with work and her son,” the insider claimed. “These are her biggest priorities.”

Witherspoon has a 12-year-old son, Tennessee, whom she shares with ex-husband Jim Toth. The former couple announced they were divorcing in March 2023 after 12 years of marriage.

“It is with a great deal of care and consideration that we have made the difficult decision to divorce,” they said in a joint statement via Instagram at the time, adding that they were “moving forward with deep love, kindness, and mutual respect for everything we have created together.”

The “Cruel Intentions” star also has two older kids — Ava Phillippe, 25, and Deacon Phillippe, 21 — with ex-husband Ryan Phillippe, whom she was married to from 1999 to 2008.

Despite initially wanting her relationship with Haarmann to be a slow burn, Page Six exclusively learned in May that she and the Searchlight Capital Partners co-founder were eying a luxe New York City apartment.

“They are looking in the area because [one of her kids] is attending NYU and Reese wants to be close,” a source told us at the time. “They’ve toured the apartment twice already and were very sweet and affectionate at both tours.”

It’s unknown whether the pair ended up moving in together or not.
