Elizabeth Banks looked gorgeous as she arrived to the Ed Sullivan Theater in NYC to tape her appearance on Late Show With David Letterman yesterday.
The What to Expect When You're Expecting star shared a photo of her very pregnant sister with David Letterman and the audience — but this wasn't just any old photo. Elizabeth and her sister Sarah were in matching wetsuits, swimming with whale sharks, aka "the largest fish in the ocean," at a Georgia aquarium.
Of course funnyman David couldn't help put poke fun at heavily pregnant Sarah, saying, "Are they [whale sharks] bigger than your sister?" OUCH!
We're sure Elizabeth is going to hear the wrath of her sister once she sees what went down on Late Show!
