Robert Downey Jr. and Gwyneth Paltrow posed together during their Iron Man 3 photocall at Le Grand Rex theater on Sunday night in Paris. Gwyneth was decked out in head-to-toe florals by English designer Erdem. It's their second stop together on a short European tour. Last week saw the duo in Munich, where Gwyneth wore KaufmanFranco to a German event. Next week, it's back to the UK for Gwyneth. She and Robert will attend Iron Man 3's London premiere Thursday, April 18. The red carpet screening had originally been scheduled for Wednesday but was pushed one day back to make allowances for crowds expected in the capital due to Margaret Thatcher's funeral.
