Gwyneth Paltrow  and Robert Downey Jr . put their famous chemistry on display when they posed for portraits on behalf of Iron Man 3 in LA yesterday. The two stars got silly during the photo shoot, with Robert sliding down the couch and Gwyneth putting her head on his shoulder. Gwyneth and Robert have been having lots of fun on the promotional trail for their new flick. RDJ gave Gwyneth kisses  on the red carpet during their press trips in Germany and the UK, which caused the actress to giggle in front of photographers. She's been making bold moves of her own, too, including playfully grabbing a comedian's crotch during an appearance on The Graham Norton Show  last week. The pair's push for their new film isn't over just yet as they will both attend the LA premiere of the movie tomorrow.
