Arnold Schwarzenegger Steps Out With Longtime Girlfriend Heather Milligan In Rare Public Appearance

Arnold Schwarzenegger and his longtime girlfriend Heather Milligan are seemingly going strong.

But the Terminator star, 78, and the physical therapist, 51, made a rare public appearance at the Austrian World Summit, which he cofounded, in Vienna, Austria, on Tuesday, June 16.

The couple stepped out to show their support for the former California governor’s Climate Initiative, which strives to extinguish pollution and ensure a healthy life is possible for everyone.

Schwarzenegger and Milligan posed for pictures with former U.S. Vice President Kamala Harris, 61, at the event.

Speaking on Morning Joe on June 16, with a nod to his famous character, Schwarzenegger said: “We have to terminate pollution. The theme of the conference is that we are unstoppable.”

Austrian President Alexander Van der Bellen, 82, and Austrian Chancellor Christian Stocker, 66, were also in attendance at the event.

Schwarzenegger and Millligan were first linked after he underwent shoulder surgery in 2012, a year after his 25-year marriage to Maria Shriver ended.

As Globe previously reported, the couple were spotted for the first time in a year when they stepped out for a dinner date at Nobu Malibu in late April.

Before that, the pair were last seen in April 2025 on a double date with US diplomat Edward Djerejian, 87, in Santa Monica.

In September, a source told Globe that Schwarzenegger’s son, The White Lotus actor Patrick Schwarzenegger, 32, was urging his father to pop the question to Milligan — after he married model Abby Champion, 29, last year.

“The whole family loves Heather, she’s a very positive influence on Arnold and held his hand through all his dramas and medical struggles these past few years,” the source explained. “He’s very wary about formalizing their status, but that’s totally at odds with how she feels.”

The source added that “it’s common knowledge she’s frustrated Arnie’s been dragging his heels for years now.”
