The comedian took on the “Moose Burger Challenge,” which, he tweeted, consists of “2lbs Beef, 1/2 lb Bacon, 1 Tomato, 1/2 Head Of Lettuce & Fries!” It did prove to be quite difficult for the late-night host, who later tweeted, “1/4 down. Already sweating, blurred vision - hallucinations... not gonna make it.” Gwyneth PaltrowWhile preparing to promote her cookbook, Gwyneth Paltrow snapped this photo as she got her makeup done.
