Arnold Schwarzenegger turned heads in Vienna on Tuesday when he appeared alongside longtime girlfriend Heather Milligan, marking one of the couple's rare public appearances together.

The 78-year-old action star and former California governor stepped out with Milligan, 51, at the Austrian World Summit together on the world stage.

Schwarzenegger and Milligan posed for photos at the event alongside former Vice President Kamala Harris, Austrian President Alexander Van der Bellen and Austrian Chancellor Christian Stocker.

While Schwarzenegger is regularly seen at red carpets, conferences and public appearances around the globe, his relationship with Milligan has largely remained out of the spotlight despite the couple having dated for more than a decade.

In 2025, the couple was spotted at an Oktoberfest event together and at the season 2 premiere of Schwarzenegger’s Netflix show "Fubar."

Their latest appearance offered a rare glimpse at the woman who first entered Schwarzenegger's life not through Hollywood, but through physical therapy.

Before she became the actor's longtime partner, Milligan was helping him recover from a shoulder injury.

The couple first met in 2012 after Schwarzenegger underwent shoulder surgery while preparing to film "Escape Plan" with Sylvester Stallone.

Stallone reportedly recommended Milligan, an accomplished physical therapist, to help get his co-star back into fighting shape.

Years later, Schwarzenegger revealed he still credits Milligan with helping keep him healthy.

"Heather Milligan is not only my girlfriend, she’s also a great, if not the best, physical therapist in the world," Schwarzenegger said during a 2024 appearance on his Pump Club YouTube channel.

"That’s actually how we met. She fixed my shoulder, but we’re not here to talk about our relationship, we’re talking here about physical therapy. And since she has been treating people, thousands of patients: football players, basketball players, UFC fighters, boxers, track and field athletes, young kids, old kids, anyone and everybody, I’m talking about thousands, she knows how to take care of joints."

The actor split from ex-wife Maria Shriver in 2011 after more than two decades of marriage. The former couple shares four children: Katherine, Christina, Patrick and Christopher. Schwarzenegger is also the father of Joseph Baena, whom he shares with former housekeeper Mildred Patricia Baena.
