Reese Witherspoon: Late Show Lovely

Out promoting her new movie, Reese Witherspoon added a touch of glamour to the Ed Sullivan Theatre as she arrived for a taping of the "Late Show with David Letterman" on Tuesday evening (November 25).

The 32-year-old actress is currently in New York City as she continues to try and boost ticket sales when "Four Christmases" hits theaters beginning on Wednesday (November 26).

Meanwhile, Reese recently shot down reports of tension between her and co-star Vince Vaughn on the set of their new holiday season comedy.

"Every co-star I ever work with I'm either having an affair with him, I'm about to get married with him, or having a baby or we absolutely cannot stand each other," Witherspoon, 32, told press of the gossip rumors.

"We got along great, we were very good friends and we were very much partners on this movie," added Witherspoon. "Vince is the funniest person I've ever worked with. It was a challenge for me to stay there and keep up with him. But I feel really a better actor for that experience."
