Robert Downey Jr. found himself taking a little, ah, romantic direction from his Iron Man 2 costar Gwyneth Paltrow during a crucial moment in the movie – while their spouses watched from off camera.
The hotly anticipated summer movie features a passionate kiss between Downey s superheroic Tony Stark and Paltrow’s long-suffering Pepper Potts.
“It was great,” said Paltrow, with more than a hint of playful sarcasm in her voice during a press event in Los Angeles Friday, “because both his my husband and his wife were right there on the set.”
