Ryan Reynolds brought his smoldering good looks and shorter hairdo to CinemaCon in Las Vegas last night. He joined Blake Lively at the convention, held at Caesars Palace, for their movie, The Green Lantern. Blake was honored with an award at the event that also brought out The Help's Emma Stone and pals Cameron Diaz and Drew Barrymore. Ryan is gearing up to start promoting his Summer film following a stint in South Africa, where he was filming Safe House. He did more than just work during his time on set, though, and kicked off a new Spring romance with model Agnes Fischer when he was away from the cameras.
