Simon Cowell & Lauren Silverman's Photos Together Through the Years

Simon Cowell and Lauren Silverman share a smooch in 2013 while out in Beverly Hills.

The pair's relationship dates back to 2004, when Silverman was still married to Cowell's friend, real estate mogul Andrew Silverman. When news broke in 2013 that Cowell was expecting a baby with Lauren, the Silvermans filed for and finalized their divorce.

Cowell called that period "difficult," but "that's all been settled now," he shared with PEOPLE in late 2013. "I love her and I love the fact that I'm having this baby."

On Jan. 11, 2022, PEOPLE confirmed Cowell and Silverman were engaged.

"From that moment I saw the [ultrasound] scan, I was like 'That is it, I'm besotted,' " Cowell said on The Kelly Clarkson Show in May 2021. "Now I just cannot imagine my life without him. He's the most amazing thing that ever happened to me. I adore him."

"I have three boys now, including him. He's lots of fun, he makes us all laugh a lot," Silverman, also mom to Adam from her first marriage, told PEOPLE in May 2020. "I think Simon has changed me. He makes me laugh all the time. I can't get angry with him because when I'm trying to be cross, he just makes me laugh."

"I am the happiest now than I have been for a long time," he told PEOPLE months prior.

On Christmas Eve 2021, Cowell proposed to Silverman in Barbados, where they first met and frequently vacation.

"They are both super happy," a source told PEOPLE of the newly engaged couple. "They've been together a long time now and adore each other so it's not a huge surprise to their close friends."
