"I completely overdo Valentine's Day! I mean, there's not just one card, there are cards hidden around the room, and sometimes things even spill into the next day — it's completely silly," he said. "If there's an excuse to have some fun, I overdo it! At Christmas, I go crazy with the tree lights and fairy lights — totally overdo it."

The 80-year-old English musician and the businesswoman, 63, have been married since 2011, and it has made McCartney happy to be the person she "relies on."

He continued: "I am very proud, in fact, to be 'The Guy' there. And I know she is grateful. So, that's my role as a husband: it's to be the strength and the romance at the same time. I don't think I consciously chose to be that way. It's just how I do things."

While McCartney's marriage to Shevell is his third, a source told PEOPLE shortly after their engagement in 2011 that "they have the right chemistry," adding that "they're both cool, chilled out and optimistic."
