"I had to marry someone as tough as me. Guy's definitely tough. He doesn't give in," The Daily Telegraph quoted Madonna as saying in an interview with Elle magazine. "But he's obviously been put in front of me to teach me things and vice versa. I had to marry a challenge, otherwise I would just get bored. Whatever else Guy is, he's never boring."
The singer said she doesn't understand why other people are so interested in her relationship with him, however.
"Posh and Becks are much more interesting. Maybe even Camilla and Charles," she said.
Discussing how she stays in such great shape, Madonna told Elle she spends two to three hours every day in the gym and adheres to a strict macrobiotic diet, the Telegraph said.
"There are no short cuts to being Madonna. It's all about hard work," she said. "There is no easy way. If you want to know how I look like I do, it's diet and exercise and constantly being careful."
