The representative gave no further details, but the Sun reported that the pair got engaged during a recent break to Barbados.

Cowell, aged 62, and Silverman, now 44, began their public relationship in 2013, shortly after Silverman's ex-husband and Cowell's close friend, Andrew Silverman, filed for divorce in July, claiming the pair were involved in an extramarital affair.

"The X Factor" creator and Silverman, a New York socialite, welcomed their first son, Eric, in 2014.

Silverman also has a son from a previous marriage.

When previously asked on fellow "American Idol" alum Ryan Seacrest's radio show if he planned to marry Silverman, Cowell said, "Let's put it this way, I wouldn't expect her to be a single mother."

The reality TV executive told Britain's OK!

magazine in November that he and Silverman are "closer than ever," revealing the "romance is still alive" between them.

"Covid-19 was the real test," he said.
