David Letterman made waffles smothered in butter for Kate Hudson when she visited his show Tuesday night. She insisted on eating only three bites, citing a new diet.

"It's so much butter!" Kate said. "What kind of butter is it? I don't really want to eat this."

Finally she tore a bite of waffle off and, while chewing, announced she has been counting calories.

"Because you've let yourself go," Dave joked.

"But I do, I actually do let myself go," Kate insisted. "And I've been calorie counting and it works. So right now this is -- about three bites is like a hundred calories."
