Catherine Zeta-Jones
Honestly, Catherine Zeta-Jones doesn't really have much of a personality when she's off-screen, confining most public knowledge about her to what she shares in interviews. However, according to some eyewitnesses, she once told an 8-year-old fan who wanted to be an actress that she was "pretty enough, I suppose" for the job. It's not all about looks, but Zeta-Jones apparently needed to remind her young fan that appearances are what matter in this industry.
