Katherine Heigl was snapped returning to the Ritz-Carlton in NYC last night, and shortly after that we spotted the actress stepping out of the hotel for a dinner date with Life As We Know It co-star, Josh Duhamel. Katherine couldn't stop giggling, and we know there's nothing going on with these two (duh, he's married to Fergie) but we have to wonder what the duo talked about as they noshed on yummy cuisine at David Burke's Townhouse restaurant!
