The funnyman was in town to premiere his hit comedy The Hangover, but Cooper, 34, and Zellweger, 40, also clocked plenty of private time together. The two were first spotted at JFK airport hopping a flight to Spain. Later, they were photographed at the luxury Hotel Arts Barcelona – Cooper with his arm around Zellweger while she tucked her hand into his back pocket.
