Earlier this week, Sir Rod cut a stylish figure on Thursday evening as he attended the 50th Anniversary Party of London private members club Mark’s Club.

Rod teamed his statement blazer with an unbuttoned white shirt, adding a white pocket tissue and a pair of black trousers. 

Accessorising, the Forever Young singer donned a collection of layered necklaces which gave a nod to his Celtic background. 

Standing alongside her husband, Penny donned a black wrap mini dress for the evening, which was emblazoned with dark sequins. 

Her blonde locks were styled in a brushed out yet structured wave, as she added a silver key pendant necklace.

And it was a family affair, as Rod and Penny’s 16-year-old son wrapped an arm around his dad for some snaps.

The up-and-coming model donned a pair of checked trousers, a cream turtleneck jumper and taupe blazer.
