Katie Holmes suri cruise heels trench scarf david letterman

Katie Holmes cleans up quite well. The usually casual actress looked absolutely gorgeous in a black trench coat and nude heels while visiting The Late Show with David Letterman.

Tom Cruise's 32-year-old wifey was there to promote her new comedy with Adam Sandler, Jack and Jill ... hitting theaters today. Good thing Katie is smiling for the cameras unlike some unflattering photos of a scary-looking little Suri.

The former Dawson's Creek star is currently filming Responsible Adults opposite Gossip Girl's Chace Crawford.
