Lillian Muller (Then)

Muller earned fame as the teacher in the 1984 Van Halen clip for 'Hot for Teacher.' Believe it or not, the actress was in her 30s when she strutted in a blue bikini as a chemistry teacher in the famous clip. To this day, she's never seen the video. Muller also starred in the Rod Stewart clip for 'Do Ya Think I'm Sexy?'
