Ananova:

Madonna says Britney Spears often asks her for career advice and says she treats the young singer like her little sister.

She made the comments on the Jay Leno show in the US.

Madonna told the chat show host: "I see her as my little sister. She asks me (for) career advice."

She added: "For the most part I try to make her understand this isn't real life and she can't take everything people say seriously. I can understand some of the stuff she's going through. I help her with that."

Madonna also talked about her relationship with Guy Ritchie, reports The Sun.

She told Leno: "Marriage isn't easy. It is a challenge especially if there are two strong-willed people who get together. Guy likes chaos, and I like order."
