PAUL RUDD ENJOYED MICHELLE PFEIFFER

Paul Rudd and sexy Michelle Pfeiffer

Paul Rudd says straddling Michelle Pfeiffer in her underwear was his best ever "first day at the office".The 38-year-old comic actor - who plays Pfeiffer's toy boy lover in the romantic comedy 'I Could Never Be Your Woman' - has revealed his memorable first scenes involved him taking pictures of his stunning scantily-clad co-star. He told the August issue of Playboy magazine: "On the very first day of shooting, we did a scene in which Michelle and I are in our underwear, and I'm straddling her and taking pictures of her with my cell phone."It was a very cool first day at the office, let's just say that."The film, due to be released this September, sees Pfeiffer, 49, play an ageing professional who falls for a younger man. Rudd - who made his name in cult movies 'Anchorman: The Legend of Ron Burgundy', 'The 40 Year Old Virgin' and as a recurring character in hit sitcom 'Friends' - can next be seen getting steamy with Jessica Alba in 'The Ten' out next month.
