Camilla, Duchess of Cornwall, is opening up about her marriage to Prince Charles.

In an interview with British Vogue to celebrate her 75th birthday on July 17, the future queen consort revealed how she and her husband of 17 years maintain their relationship amid their busy work schedules.

"It's not easy sometimes, but we do always try to have a point in the day when we meet," she told the magazine. "Sometimes it's like ships passing in the night, but we always sit down together and have a cup of tea and discuss the day. We have a moment."

According to the duchess, it's always "lovely to catch up" when she and Prince Charles, 73, "have a bit of time." She also shared that their time together is usually "very relaxing" for her.

"You know, when we go away, the nicest thing is that we actually sit and read our books in different corners of the same room. It's very relaxing because you know you don't have to make conversation. You just sit and be together," she explained.

Camilla and Prince Charles had a relationship before both married other people. She tied the knot with Andrew Parker Bowles and had two children, Tom, 47, and Laura, 44, with him before they divorced in 1995.

Prince Charles went on to marry Princess Diana and welcome sons Prince William and Prince Harry. The royals separated in 1992 and were officially divorced in 1996 following infidelity from both parties.

In 1998, the Prince of Wales introduced his sons to Camilla, and the couple later tied the knot in 2005, according to People.

When asked about her "me time," Duchess Camilla told British Vogue that she loves gardening, going for a walk and just sitting down and reading a book. Having these moments is her "idea of heaven" when she's "in the quiet of the countryside, where you can generally relax and properly think."

"I suppose what I'd think is, 'I'm quite lucky that I'm still around,'" she added.

Camilla also revealed how she bonds with her five grandchildren, who are aged 12 to 14. She said she loves texting them, explaining that their conversations allow her to learn from young people and vice versa.

"You know the nice thing about being a grandmother is that you can spoil them occasionally, give them more of the things that their parents forbid them to have," she said.

As for her upcoming birthday, Duchess Camilla said that "there won't be much celebration." She intends to spend the day with her family and a few friends.
