In case you were not aware of the“mystery of the missing mole,” Sarah Jessica Parker has some news for you: She "didn't think a thing" about removing it...at first. "Then apparently it turned into mole-gate." The actress told David Letterman last night that after having the procedure done in 2008, she was surprised when a woman approached her, upset that SJP's “signature” trait was missing. "I was like, 'My mole was my signature? Isn't my brain my signature?'" Watch the clip.
