Matthew`s girlfriend never gets muddy

Los Angeles: Hollywood heartthrob Matthew McConaughey says that his girlfriend, Brazilian model Camila Alves, looks beautiful even after long treks, which leave him muddy and sweaty.

One of McConaughey`s most memorable workouts was a hike he took during a trip to French Polynesia with Alves, 28, the mother of his two children Vida, 1, and Levi, 2, reported People magazine.

"We went up to 3,000 feet and I had on hiking shoes and I was all set up and ready to go. Camila was wearing Hawaiian sandals and a white skirt. I came down to the bottom of that hill afterward and had blood on me, all muddy and that girl didn`t have a speck of dust on her, looking beautiful," said McConaughey.

As for his workout preference, McConaughey enjoys using heavy rocks to help maintain his trim physique.

"You get a full-body workout just by finding out how many positions you can manage without having to set the rock on the ground," said the actor who is a self-confessed exercise freak.

"I`m not a professional athlete. But I have a job where I like to look good and be as healthy as possible," he said.
