Mr. Pop History – That’s right and the girls made their first Pepsi appearance, singing behind Ray Charles on a Super Bowl Diet Pepsi ad in 1991. After that, they took on a life of their own – so-to-speak. After all – no one sang “Uh-Oh” better.

They appeared on talkshows, supermarket openings – you name it. Several years later, it all came to an end – because – the girls weren’t helping sales – and it didn’t help that they wanted to become more “serious” as music artists – afterall – they were lip-synching on commercials and in appearances.

The “Uh-Oh” girls were Darleen Dillinger, Mellani Paul and Gretchen Palmer. They only appeared only on Diet Pepsi soda labels in Japan – because over there, they were extremely popular. Here’s a picture of a Japanese Diet Pepsi soda bottle from 1993.
