The Smitten Factor! Cheryl Fernandez-Versini cuts a sexy figure in plunging fishtail frock as she cosies up to husband Jean-Bernard at Simon Cowell’s birthday

It might have been Simon Cowell’s big night.

But all eyes were on one couple when they made their entrance to the music mogul’s 54th birthday celebrations at swanky London restaurant Scalini in Chelsea on Sunday evening.

Newlyweds Cheryl and Jean-Bernard Fernandez-Versini, who tied the knot in a secret ceremony in Mustique in July, looked happier than ever as they made their way into the Italian restaurant.

Jean-Bernard kept a protective hand around The X Factor Judge, who dazzled in a sexy metallic pink frock with a low-cut bustier top and fishtail hemline.

Cheryl finished off her look with nude pumps and a reflective mini clutch. The 31-year-old shunned any statement jewellery and instead let her jaw-dropping platinum princess-cut diamond engagement ring and diamond encrusted wedding band do all the talking.

Her shiny chestnut tresses were swept up into a sleek chignon hairstyle while she worked a nude lip and smokey eyes.

Meanwhile Cheryl’s handsome husband looked just as stylish as his popstar partner in a deep blue navy suit, a white unbuttoned shirt and black shoes.

According to witnesses at the party, the duo’s amorous display carried on well into the night.
