Beach before baby! Simon Cowell and his pregnant girlfriend Lauren Silverman are taking full advantage of their downtime before their son arrives. The couple was spotted taking a relaxing stroll in Bridgetown, Barbados on Thursday, Dec. 26.

During the getaway, the 54-year-old X Factor judge and creator was photographed shirtless while wearing blue-patterned beach shorts. Meanwhile, Silverman, 36, stunned in a form-fitting navy one-piece bathing suit that showed off her toned legs and big baby bump. 

In her last trimester, the lovebirds have been nothing but affectionate toward each another. The New York socialite often visited Cowell during tapings of the FOX reality series, and the British personality organized a baby shower for Silverman earlier this month. 

On Dec. 8, Silverman enjoyed an intimate get together -- with Cowell's exes Mezhgan Hussainy and Terri Seymour in attendance -- at his Beverly Hills home. "She had her hand on her tummy a lot," an insider said of the second-time mom-to-be to Us Weekly. "She kept rubbing it, and she looked really proud." 

"They seem to really be in love," another source added. "I've never seen him like that before."

Silverman is already a mom to son Adam, 7, with ex-husband Andrew Silverman.
