Now, the pair is expecting their first child together. Congrats to the happy couple!
In May 2017, Kerr and Spiegel tied the knot at their home in Brentwood, California. The wedding was an "intimate affair" with about 50 guests in attendance, many of whom "high-profile" or models.
Kerr was at the initial public offering to support Spiegel, sending snaps with early Snapchat employees on the floor of the stock exchange.
Snapchat has been undaunted, though. Spiegel took Snap public in March 2017. He's now estimated to be worth about $2.9 billion.
Despite her use of Instagram, owned by Facebook, Kerr says she "cannot STAND Facebook" and has been "appalled" at the features it has copied from Snapchat and her fiancé. "Can they not be innovative?" she said. "Do they have to steal all of my partner's ideas?"
In July 2016, Kerr announced their engagement by using Bitmojis from Bitstrips — a company Snap had just bought for $100 million — to show that Spiegel had popped the question. 'I said yes!!!' Kerr said in her Instagram post.
Mostly, though, the pair loves hanging out together.
While their relationship is mostly private, the duo makes some high-profile appearances like a May 2016 dinner at the White House last year with President Barack Obama.
In May 2016, the couple went all-in and purchased a 7,100-square-foot house for $12 million in the Brentwood neighborhood of LA.
Even though the two stay busy with work, Kerr says Spiegel loves to come home and chill with the family. "He's 25, but he acts like he's 50. He's not out partying," Kerr once said. "He goes to work in Venice [Beach, in LA]. He comes home. We don't go out. We'd rather be at home and have dinner, go to bed early."
Spiegel stays busy as the CEO and cofounder of Snap, the parent company of the photo-messaging app Snapchat. It has been a busy year for Spiegel, who took Snap public in March.
Kerr, 34, was once married to Orlando Bloom and has a son, Flynn. Spiegel had to wait at least six months to meet him, per Kerr and Bloom's rules, but "things are going well," Kerr said. "We're just a modern family now."
In 2007, Kerr was the first Australian to become a Victoria's Secret Angel and was among the world's highest-paid models. Now she's working on creative projects like jewelry lines and just launched a handbag collection in Asia.
The two met at a dinner for Louis Vuitton in Los Angeles. "We were really good friends for a long time before we started dating," Kerr told The Sydney Morning Herald.
