Madonna "hates" her own music.

The 55-year-old singer is tired of hearing her own songs so would never work out to a soundtrack of her own material. "I don't work out to my music - I hate my music! I mean, I'm sick of it. I love my music, but I'm just kind of sick of it. I like to hear other people's music when I work out," she admitted.

The "Hung Up" hitmaker - who has children Lourdes, 17, Rocco, 13, and Mercy and David, both eight - is known for her toned physique but she isn't always happy with her body. Speaking at the opening of her Hard Candy Fitness gym in Toronto, Canada, she said, "I have a love/hate relationship with my body. Some days I'm happy with it and other days... I wasn't born with Gisele Bundchen's body unfortunately, so you got to work for it - but it's OK."

Madonna - who is dating 26-year-old dancer Timor Steffens - also admitted she isn't a fan of "big bulky" guys, but does like them to be in shape: "You need to work out. I'm not into big bulky muscles, but a little more definition would be good. I like a lean, mean, fighting machine!"
