VIDEO : Hugh Grant Didn't Recognize Co-Star Renée Zellweger

Although Hugh Grant co-starred in a couple of movies with Renée Zellweger, the actor failed to recognize her on "Watch What Happens Live Thursday." Grant, who will next appear alongside Meryl Streep in "Florence Foster Jenkins," was asked a series of questions about six of his former female co-stars. When he looked at their pictures, he said, "Who is the one second from the right, because I've never seen her before in my life?" He was shocked when he was told that it was Zellweger.
