At this point in her life, you probably know Holly Madison (@HollyMadison) best for her role on the reality TV show, The Girls Next Door. She used to date Hugh Hefner and is one of the most popular Playboy Playmates of all time. But, did you know that Ms. Madison also used to model next to cars? That's right. Once upon a time, she did shoots with Lowrider as well as a handful of other car mags. So, while her name may have gotten bigger over the years, we still prefer to think of her as the girl who graced the pages of some of our favorite car mags. And, after seeing these shots, can you blame us?
