They've been dating since 2004.
Simon Cowell and Lauren Silverman, who have been dating since 2004 and had son Eric in February 2014, were engaged on Christmas Eve in Barbados, where they originally met, according to a source obtained by PEOPLE.

“They are both super happy,” an insider said. “They’ve been together a long time now and adore each other so it’s not a huge surprise to their close friends.”

In a previous interview, the longtime judge on America’s Got Talent said, “[The affair] is not something I am proud of or wanted to happen in terms of hurting anyone,” adding, “It just happened … But then, of course, you have a baby, and you look at the baby and you kinda go, ‘This is what happened from it.’”

“Lauren, you’ve been my rock for the past few years, put up with everything I put up with,” he stated at the time.
