Simon Cowell and Lauren Silverman have reunited! The X Factor judge stepped out for the first time with Silverman since Us Weekly exclusively broke the news on July 31 that the two are expecting a child together.

Looking relaxed and happy, the soon-to-be parents were photographed walking in the South of France on Friday, Aug. 23. The expectant mother -- due in February -- held onto Cowell's arm and later stopped to take photos of the British TV star sitting in a race car.

The pregnant socialite wore sunglasses and a loose-fitted blue and purple sundress for the outing, with the wind at one moment accidentally exposing her bare belly bump and underwear.

"I'm happy and excited," Cowell told Us at the London premiere of One Direction's new movie, This Is Us, on Aug. 20 about becoming a dad. "It's a great time in my life," he added.

"Lauren has loved Simon forever," a source previously told Us. "And they started having an affair four years ago." Though it started as just a fling, the relationship became more serious once Silverman became pregnant. "Simon and Lauren are together," a Silverman family source said. "They talk 100 times a day."

Silverman and her estranged husband Andrew Silverman recently settled their divorce on Aug. 14 after more than 10 years of marriage. The former couple will continue to have joint custody over their 7-year-old son Adam.
