EXCLUSIVE: Penny Lancaster looks VERY leggy alongside her stylish husband Rod Stewart as the couple join Christian and Geri Horner to celebrate the Formula 1 star’s VERY star-studded birthday

It was a glamorous evening as select stars gathered at Mount St restaurant in Mayfair on Wednesday evening to celebrate Christian Horner’s 50th birthday.

Penny Lancaster looked sensational as she showed off her slim legs in a glittery dress with a high leg slit.

The 53-year-old model opted for a dark gray sequin dress for the birthday bash, which she paired with gold glittery heels.

As the star left the restaurant, she wrapped herself in a mustard-colored fur coat and held hands with her husband.

The couple accompanied birthday boy Christian and his wife Geri, who celebrated the racing star’s milestone birthday at the weekend after the Formula 1 season came to an end.

Penny appeared to be in great spirits as she beamed at the end of the night as she headed home before the pair got into a taxi.

Meanwhile, 78-year-old musician Rod looked as stylish as ever as he spiced up his outfit with a range of contrasting patterns.

The singer wore a leopard print vest which he paired with black and white pinstripe pants.

He left the collar of his white shirt open and completed the look with a red and white scarf and a long black coat.

But the highlight of his look was of course his silver, glittering brogues, which perfectly rounded off his rock star style.

The event was also attended by Rolling Stone star Ronnie Wood and his wife Sally, as well as Spice Girls colleague Emma Bunton and her husband Jade Jones.

Ronnie and Rod are old friends, having played together in the rock band Faces, which formed in 1969.

“F1 supremo” Bernie Ecclestone also took part in the celebrations and beamed alongside his wife Fabiana Flosi.
