Project Runway host Heidi Klum got in trouble for sunbathing topless by a hotel swimming pool. The German supermodel - widely considered to be one of the world's most beautiful women - doesn't like to wear a bikini top when she sits in the hot sunshine because she hates having tan lines. Although she doesn't get many complaints when she strips off when on vacation in Europe, Heidi admits her exhibitionism didn't go down well with people at a hotel in Phoenix, Arizona.

During an appearance on The Tonight Show with Jay Leno, the 38-year-old catwalk beauty said, "I don't like to wear tops because I hate tan lines... I do have to say that I think (the general public is) more uptight here. I got in trouble once, in Phoenix. I was laying by the pool - obviously I had no top on. I'm lying there sunbathing, and this guy comes over - a security guy. He says, 'Ma'am, you have to put your top back on because we're having complaints. People are complaining that you have no top on.'"

A shocked Jay responded by joking, "Who are the idiots who are complaining?"

Although Heidi - who raises four kids, Leni, seven, Henry, five, Johan, four, and 21-month-old Lou, with her husband Seal - initially complied with the security guard's request, she then decided to strip off again, earning herself another telling off. Klum - who lives in Los Angeles - added, "I took it back off because I thought that was really ridiculous. And then (security) came again, saying, 'Ma'am you really have to put your top back on, otherwise you're going to be in trouble.'"
