Snapchat CEO Evan Spiegel proposed to his girlfriend of over a year, Australian supermodel Miranda Kerr. The engagement was confirmed by a post on the former Victoria’s Secret Angel’s social media accounts Wednesday.

The couple met in 2014 and started dating in June 2015. Last summer, Kerr brought Spiegel to a party where she introduced him to her friends. “They felt very happy and at ease,” said one of the attendees at the time, E! News  reported . “Everyone very quickly got the message, they both seem smitten.”

This will be Spiegel’s first marriage whereas Kerr, 33, was married to actor Orlando Bloom from 2010 to 2013, and has a five-year-old son with him.

“They’ve fallen hard for each other and are really in love,” an insider told E! News, months into the relationship.

“Miranda loves how down to earth and brilliantly smart Evan is,” the source said. “They have incredible conversations and can talk about anything. He comes from a wonderful close-knit and loving family and that was a real draw to her.”

Spiegel’s Snapchat is reportedly worth $20 billion with the CEO valued at $2.1 billion himself, according to Forbes.

“He’s just so nice, very normal,” the source said. “You would never know about his money. He is really down to earth,” a source told E! News.

The billionaire is also reported to be getting along well with Kerr’s son, Flynn.

“Evan is really great with Flynn and they bonded instantly,” the source said. “Evan gets down on the floor and plays with Flynn and is very fun and creative. That's so important to Miranda and a quality that really stands out about Evan.”
