Sir Rod Stewart and Penny Lancaster

The ‘Maggie May’ rocker, 78, has 27 years on his 52-year-old model wife.

The couple have been married since 2011 and have sons Alastair, 17, and Aiden, 12.

On his best marriage tip, Rod said in June: "My relationship rule is, ‘Don’t argue after a glass of wine – leave debating until the morning.'"
