Madonna has admitted it would be “less challenging” for her children if they didn’t have her as a mother.

The singer, who has six kids, says they sometimes find it difficult having one of the most famous people on the planet as a mum.

Speaking on tonight’s Graham Norton Show, she said: “I think they wish I wasn’t Madonna. I think it would be less challenging in their minds if they didn’t have me as their mother.”

Madonna has two biological children, daughter Lourdes and son Rocco, and four adopted children from Malawi – David, Mercy and twins Estere and Stella.

She also admitted to feeling anxious ahead of her upcoming world tour, which includes a string of shows at the London Palladium.

Asked if she felt excited, she replied: “Of course. I’m feeling anxiety right now. Every time feels like the first time.”

“I can see everyone (in London) and they can see me, which you can’t in a stadium or sports arena.

“I want to do something different. It’s very theatrical and intimate. I’m nervous.”

She also rubbished rumours that a biopic of her life is in the works.

She said: “If there ever is one, I’ll be directing it. I warn any director who tries to make one, there will be a mysterious death!”

The 60-year-old’s latest album, Madame X, is released today.

Her 14th album was conceived in Lisbon, Portugal, after she relocated there so her son David could attend a football academy.

She said she had unexpectedly found herself becoming a “soccer mum”.

“I surprised myself,” she said.

“Barcelona and Turin were an option, but I couldn’t see myself living there. It would have been a lot easier if he’d liked music!”

Asked if she watches her son’s games, she said, “I admit I only watch when he’s playing. If he’s on the bench, I’m on my phone.”
