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.

She admitted: ''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.''

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.

Speaking to 'Entertainment Tonight Canada' reporter Roz Weston, she said: ''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!''
