As much as we'd like to take this receipt at face value, we think it's unlikely that one of the hottest stars in the entertainment business is waiting tables in her spare time. Lady Gaga is a multi-millionaire. She doesn't have to work another day in her life if she doesn't want to.
Having said that, Gaga has been known to do strange and unusual things over the years. Perhaps she's taken on a little side hustle to fill her time between albums. We wouldn't be totally surprised!
