Patrick Schwarzenegger was seen indulging in a romantic kiss with his fiancée – before cheekily grabbing her behind in public.

The 31-year-old son of Arnold Schwarzenegger ecstatically announced his engagement to model Abby Champion on Boxing Day 2023.

His proposal came after an eight-year relationship, with the pair having struck up their romance in 2015 while Patrick was still in college.

Now the ‘nepo baby’ has achieved new heights of fame on his own, starring in the buzzy third season of the hit HBO series The White Lotus.

Over the course of the past few episodes, Patrick’s character has drawn especially frenzied fan attention because of a taboo Sєxual undercurrent in his storyline.

But when he was spotted out and about in Los Angeles this week, Patrick proved that in real life, his long-term happy relationship is still going strong.

Abby meanwhile modeled a flattering maroon sweatsuit that emphasized her pert derriere as she strutted her stuff along the sidewalk. 

Patrick has become a focal point of The White Lotus, where his character Saxon shares an incestuous kiss with his brother Lochlan, played by Sam Nivola.

Now their co-star Charlotte Le Bon, 38, has candidly revealed Patrick’s visceral reaction to the prospect of filming the lip-lock.

‘Well obviously they’re not brothers by blood, so that made it easier,’ the French Canadian actress drily remarked to Vulture.

‘I think for Patrick it was really difficult. For Sam, he was kind of like: “It’s whatever, let’s just do it well one time and it will be over.” You know? Because if you don’t do it well the first time, then you have to do it over and over again,’ she explained. 

‘But Patrick’s reaction in the episode is his genuine reaction. We all thought he was going to throw up. And Sam was like: “It’s fine, it’s just a kiss, calm down!”‘

Patrick and Abby are planning to get married this year, after their wedding was postponed so he could shoot The White Lotus in Thailand. 

Although Patrick kept mum about the time and place of his upcoming nuptials, he noted that he and Abby have ‘been together for so long, our families have become so close,’ and that he was eagerly anticipating being able ‘to finally tie the knot in a location that we love, with people we love.’

Meanwhile Abby has shared that Patrick refuses to give her any spoilers for the new season of The White Lotus, in an interview with WWD.  

‘I offered a trade to Patrick: details on my wedding dress if he gave me clues on the ending to White Lotus,’ Abby spilled, sharing that her husband-to-be ‘wouldn’t make the deal, so I’ll be watching with the rest of the world.’

Patrick dished: ‘I’ve had people stop me in the line for coffee and explain for multiple minutes of where the show was going to go.’
