Both blessed with fit physiques, it’s no surprise they are often out breaking a sweat, whether it’s going to the gym, doing yoga or simply walking the dog – a case of those who train together, stay together?

They’re style icons

Bombshell Gerber is no stranger to headlines, especially with her fashion looks, but now the supermodel has a new beau to strut with. They made their debut as a couple in March, attending W Magazine’s Best Performances event hand in hand, with Gerber in a sequinned skirt from Oscar de la Renta and Butler in a sleek suit.

Off the red carpet, they’re often seen in casual wear and gym attire, but were recently spotted in all-black matching outfits ahead of the Elvis screening in New York City.

They love a little PDA

As a relatively new couple, the lovebirds are inclined to a little – well, a lot – of PDA. Besides their hand-holding and kissing on the street, they also don’t shy away from each other at big events.

At the W Magazine event, they were photographed kissing on the cheek, but it was the Cannes Film Festival which left fans cooing like crazy. According to People, they walked the red carpet separately, but once reunited, they couldn’t stop smooching, laughing and gazing into each other’s eyes. Aww.

They travel the world together

They’ve both got busy schedules, but make the relationship work by jet-setting the world together. In February, Gerber and Butler took their romance off to London for Valentine’s Day, and were also spotted in Paris the month after. We can’t wait to see where else their journey together takes them.

The 10-year age gap

But Gerber previously told Vogue she doesn’t think too much about it: “I had never had a high school sweetheart or anything. And so I tended to date older people because those were the people I was around.”

Now 20, she’s faced some scrutiny for the 10-year age difference between her and the Elvis star. “Austin is older than her by 10 years, but she likes that,” an insider told Life & Style in December last year. “They‘re having fun getting to know each other better, and they make a really cute couple.”

Despite the PDA, they are actually very private

It’s rather obvious that the sweethearts are happy in love and go above and beyond in supporting one another in their careers. But despite the PDA, they are both private about the relationship and Butler even avoids the topic when asked, like in his recent GQ interview: “I don’t think there’s anything I want to share about that,” he responded when asked about his romance with Gerber.

Gerber also told i-D before in an interview: “You have to silence the outside world. The only people who know anything about anything are the people in the relationship.”

Gerber’s mum Cindy Crawford approves

It can be quite intimidating when the mother of your better half is one of the most renowned models of the century. But thankfully, Butler has mum’s approval, according to Grazia. A source also said that Crawford is “supportive of the relationship and only wants to see Kaia happy”.

Who have they dated before?

She’s also been romantically linked to Davidson and Wellington Grant before that.
