Barr returned to stand-up comedy but with a notably different appearance: she has lost some weight, dyed her hair blonde, and had plastic surgery, which she does not recommend - "Now I realize that everyone has to get old and die, but it was still a very bad experience.... No one looks better after plastic surgery. Just pink and shiny. At the end of it, you look like an idiot." Barr claims that some of her surgery was for health reasons; she had a rhinoplasty to correct sleep apnea; while her breast reduction surgery was to reduce back pain.
Barr has written that she considers herself a kabbalist and a follower of Jesus Christ.
Barr told James Rampton of The Independent that fame went to her head. Barr, who had worked as a window dresser and waitress in Denver, said she had become famous quickly and lost touch with reality. "I was in a sound studio for almost a decade. At the end of it, like Rip van Winkle, I came back and found that everything had changed. Suddenly there were computers and e-mails, and it took me another 10 years to catch up with regular people. But the TV show is over. What am I going to do?"
