Mary-Louise Parker: Letterman Late Night!

Mary-Louise Parker is drop-dead gorgeous in an asymmetric dress outside the Ed Sullivan Theatre for the Late Show With David Letterman on Tuesday (August 25).

The 45-year-old South-Carolina born Weeds actress returns next Monday for the final episode of Season 5 on Showtime.

She recently commented about dating as a single parent, saying, “Some men are daunted by it; some are really attracted. I had someone ask, ‘Does this mean we can’t go out anytime we want?’ And I said, ‘Yes, that’s exactly what it means. It means you come fourth, ’cause it’s my kids, my job, my family! ”
