Who would win in a fight, Juliette Lewis the actor or Juliette Lewis the rock star? Hmm. I have some swabs arounds here somewhere...
Combine their DNA to make some sort of Serpentor type creature. Maybe Juliettor. She can sing and act. Edit: I thought you were talking about some singer I didn't know about that had the same name, but I guess the actress is a singer now.
She's been in music for quite awhile now, her first album was released in 2004. Unlike most actors turned musicians, she is actually supremely awesome. http://www.myspace.com/juliettelewis It was the best club show I've seen in years. Amazing!
