Kristen Bell's "Tonight Show" Stop

Stepping out to fulfill some promotional duties, Kristen Bell made an appearance on “The Tonight Show with Conan O’Brien” last night (October 6).

The “Forgetting Sarah Marshall” actress looked lovely in a strapless frilly black dress with matching peep-toe heels as she chatted with the crimson-haired talk show host.

Kristen has been working overtime promoting her upcoming movie “Couples Retreat” all over the globe, from Australia to the United States.

And we only have 2 days to wait until the sure-to-be hit flick hits theaters Stateside on Friday, October 9th. Jason Bateman, Vince Vaughn, Kristen Davis, and Malin Akerman also star.
