When Were Lewis and Kaia First Spotted Together?

The birthday dinner was a family event. Kaia was spotted with Lewis and his father, actor Bill Pullman. That’s a pretty major step—meeting the parents, right?

“They’re a cute couple and very low-key.”

What Happened Between Kaia and Austin Butler?

Before Lewis, Kaia Gerber was in a three-year relationship with Austin Butler. Butler is best known for playing Elvis in the biopic and his role in Dune: Part Two.

They made their red carpet debut in March 2022, and their romance was high-profile for a while. But the relationship came to an end in late 2024. According to reports, the split was amicable and stayed private for some time before word got out.

Did Lewis Pullman Bring Kaia to the Thunderbolts Premiere?

That’s where things get interesting.

While Lewis is starring as Robert “Bob” Reynolds / Sentry in the Marvel film Thunderbolts, which releases May 2, he attended the red carpet premiere on April 28 solo.

When asked by People Magazine if he brought a date, Lewis replied with a smile and a laugh:

“Well, listen — we’re all just lucky to be here on the carpet, hanging, we’re looking forward to Thunderbolt.”

So, no Kaia by his side at the premiere. But his response wasn’t a denial either—just keeping things private, perhaps.

What’s the Age Difference Between Lewis and Kaia?

Lewis Pullman is 32 years old as of 2025. Kaia Gerber is 23. That’s a 9-year age gap.

Both come from Hollywood families. Lewis is the son of Bill Pullman, and Kaia is the daughter of supermodel Cindy Crawford and businessman Rande Gerber.

So, while their careers are different, their backgrounds definitely give them something in common.

What Projects Are They Working On Now?

Lewis Pullman is having a breakout year. Aside from Thunderbolts, he’ll also be appearing in Avengers: Doomsday, expected in 2026. He’s already impressed audiences with roles in Lessons in Chemistry, Outer Range, and Bad Times at the El Royale.

Kaia Gerber is expanding her range, too. She’s been active in fashion and has taken on more acting roles. In March 2025, Lewis’s parents even attended her theater performance in Evanston Salt Costs Climbing in Los Angeles. That’s another sign things could be serious.

Are They Keeping Things Private on Purpose?

It sure looks that way.

A source told People that Lewis and Kaia have been spending time together quietly. They’ve been seen visiting low-key bars and restaurants in Los Angeles, dressed casually and avoiding flashy public outings.

When you’re constantly in the spotlight, it makes sense to want to keep some things personal.

What Were They Wearing at Their First Public Outing?

Fans love to know what celebrities wear—and this pair didn’t disappoint.

During their January dinner:

• Kaia Gerber wore a blue denim jacket with matching jeans.
• Lewis Pullman kept it casual with a bomber jacket, white t-shirt, trucker hat, and boots.

It was a relaxed, no-pressure kind of outing. But their chemistry was easy to spot.
