David Letterman ran through a list of rumors about Lady Gaga on 'Late Show' (Weeknights, 11:35PM ET on CBS) so she could clear up the truths from the lies. She was very casual and calm in her replies, but Letterman was stunned by some of them.

On her meat dress being preserved as beef jerky: "Yes." On if she relaxes by fly fishing: "No." Did she eat a Barbie doll's head during a stage production? "Yes. All the time."

At this, Letterman had to stop as he simply refused to believe it. So Gaga took the questions and proceeded to tear them up. Then, as he was looking for another one, she put the paper in her mouth and started to chew, refusing to spit it out. "It's delicious," she insisted.

Letterman insisted it was laced with chemicals and was gonna make her sick, which prompted her to feign passing out. After watching her having so much fun on the 'Saturday Night Live' season finale this past weekend, clearly Gaga is on a silly streak right now, which is making her appearances very entertaining to watch.
