"Fuzzy picture but i love it. Kate and I during Christmas family photos," David shared with his followers. "We had so much fun that day. She was so sharp and quick on her feet. She could make me laugh so hard. I still can't believe it."
He added in a separate Twitter post, "Katy at my book signing. I love this pic of her. So pretty. I dont think everyone knew how f--ing funny she was... Its a rough world out there people. Try to hang on."
