Heidi Klum's career has taken her far — she's the first German model to become a Victoria's Secret Angel, she's currently a judge on America's Got Talent and cohost on Amazon's Project Runway-esque show Making the Cut. But beyond her hosting and modeling gigs, Heidi's ambitions have also led to her marrying musician Tom Kaulitz.

Per an Us Weekly insider, Heidi, 48, was introduced to Tom, a 32-year-old guitarist of the German rock band Tokio Hotel, while she was hosting Germany's Next Top Model.

Right away, the two discovered they shared a lot in common. Both Tom and Heidi had been married before — Heidi was married to celebrity hairstylist Ric Pipino between 1997-2002 and singer-songwriter Seal between 2004-2015; Tom was married to Ria Sommerfeld from 2015-2018, despite splitting up with her in 2016, per Women's Health. They also were both born in Germany.

"He’s German [too], so it’s been fun and easy for Heidi," the source told Us Weekly. 'Tom is a breath of fresh air for her. They fell into an easy rhythm really quickly.”

It wasn't until around early 2018 that the two reportedly "made their relationship official." Apparently, an appearance together at a West Hollywood party hosted by jewelry designer Lorraine Schwartz in mid-March of 2018 confirmed their relationship status. After that, the couple was spotted together while Heidi filmed season 13 of America's Got Talent and when the two took a romantic vacation to Cabo San Lucas, Mexico later that same spring.

Throughout the summer and fall of 2018, their love continued to be documented in front of red-carpet cameras as they attended a formal Cannes Gala and the Emmy Awards. Most notably, the duo dressed up as Princess Fiona and Shrek for Heidi's iconic Halloween bash in New York City.

At the time, Heidi gushed about her man to People, calling him "absolutely wonderful."

"He is the kindest, sweetest, most caring, loving person. I feel so lucky. I don’t know the last time I was this happy in my life," she told the magazine. "He is absolutely wonderful. Maybe it is because he is German and we understand each other in a different way. But so far so good."

After about eight months of dating, Heidi announced on social media that she and Tom were engaged. "I SAID YES ❤️," the AGT judge wrote alongside an up-close picture of the pair and her teal sapphire engagement ring. According to what a source told People, Tom sought a special blessing from Heidi's kids — daughters Leni, 18, and Lou, 12, and sons Henry, 16 and Johan, 15 (Leni's biological father is Italian businessman Flavio Briatore; she was adopted by Seal. Heidi welcomed Henry, Johan and Lou with Seal).

On February 22, 2019, Heidi and Tom made things official, despite details about their nuptials not coming out until July of that same year. Then, Vogue reported that the couple organized a second ceremony on the Christina O, a yacht belonging to Jackie Kennedy Onassis's second husband, Aristotle Onassis, in Capri, Italy on August 3, 2019. Today, the couple appears to be going strong.

Throughout their relationship, Heidi has had to field questions about their 17-year age gap. But as Heidi has made perfectly clear, outsider opinions don't matter to her or Tom — they're happy to be together no matter what anyone else says.

"Lots of people are questioning that and asking about it," she told InStyle back in 2018. "That’s really the only time when age seems to be shoved in my face and I have to give an answer for it."

She continued: "I don’t really think about it that much otherwise. You have to just live a happy life without worrying too much about what people think because worrying is only going to give you more wrinkles."
