Big Bang Theory's Kaley Cuoco was spotted outside of the Ed Sullivan Theater this afternoon. The actress was heading inside the theater for an appearance on the 'Late Show With David Letterman' tonight.

Some guests choose to wait and get dressed at the theater and that's a bummer for us because then we have to wait to see what they wear on the air. She does look fantastic in her casual outfit, too. ;)

Are you a fan of the show?
