Lauren Silverman cuddles up to Simon Cowell as her husband looks on

Simon Cowell and Lauren Silverman were pictured together, as they enjoyed a cozy Caribbean holiday in January 2012 alongside her husband Andrew Silverman.

Although real estate mogul Andrew Silverman was just a mere matter of feet away, his wife was seen tenderly running her hands through the hair of Simon Cowell.

Enjoying a new year break in St. Barths, Simon Cowell and the Silvermans seemed to be in high spirits as they sat on-board Cowell’s luxury yacht soaking up the sun as the sipped on glasses of orange juice.

And while the group appeared to be chatting away amiably, the pictures show Simon Cowell certainly only had eyes for one of the Silvermans, with him seeming utterly unable to distract himself from the alluring Lauren.

With Andrew Silverman looking on, Simon Cowell leaned in closely to the stunning socialite, with a smirk spreading across his face as he indulged in a close conversation with the beauty.

But it wasn’t long until the property entrepreneur got some quality time with his wife, with the tables turning as he tenderly cupped Lauren’s bottom as Simon Cowell looked on.

Rather than suffer an attack of the green-eyed monster, the star appeared utterly amused by the entire debacle, and grinned away as he stared at the couple.

After the two men enjoyed a brief chat, Lauren Silvrman and Simon Cowell made their way over to a sun lounger, where they kicked off a rather friendly display.

Reclining with their heads tilted into each other, the pair appeared to be sharing a joke as they giggled away in the sunshine.

And despite her husband being in full view, Lauren Silverman seemed to throw caution to the wind as she ran her hands through the music mogul’s hair, with the duo even posing for a phone picture together at one point.

Following their playful display, Lauren Silverman hopped up off the lounger, and appeared to bend down to treat the star to a friendly peck.

While her face couldn’t be seen in the angle of the shot, Lauren Siverman put her arm across Simon Cowell as she leaned into him with her hair tumbling around her shoulders.

After his close pal wandered off to another part of the yacht, Simon Cowell was left looking like the cat who’d got the cream as he stretched out with his arms behind his head and a huge smirk on his face.

A close friend of Simon Cowell confirmed on Wednesday afternoon that Lauren Silverman was expecting his child, and claimed she wanted to marry him.

Although Lauren Silverman and her husband, who have a son together, have holidayed together on numerous occasions over the past four years, it wasn’t until the socialite and her real estate mogul husband ended their union around a year ago that her friendship with Simon Cowell turned to romance.

Lauren Silverman is said to be “around 10 weeks along” in the pregnancy, according to Us Weekly magazine.

Simon Cowell and Lauren Silverman’s situation is made more complicated by the fact that she is still married to Andrew.

But a source told Usmagazine.com: “Lauren and Andrew have been unhappy in their marriage for some time, and their divorce has been in the works for a while. As their marriage deteriorated, she and Simon became close.”

Simon Cowell, 53, and Lauren Silverman, 36, have been seeing each for at least a year, according to friends, and were even seen viewing houses together in Los Angeles earlier this year.

He made no reference to impending fatherhood when he opened up to Chelsea Handler during an interview on her talk show on Tuesday night, sticking to topics including One Direction and his recent health kick.
