She endured a 14-hour flight from Los Angeles, but you’d never know it when a pregnant Reese Witherspoon showed up at the Cannes Film Festival on Saturday in a form-fitting black jersey dress that showed off her bump.
Witherspoon, who also wore dangling diamond earrings and sky-high fuchsia stilettos, flew to Cannes with her husband Jim Toth to promote her new movie, Mud, which premieres Saturday at the festival.
The actress’s presence at Cannes while pregnant was all the more surprising given what a small role she has in Mud.
The new film, written and directed by 33-year-old indie darling Jeff Nichols, stars Matthew McConaughey as a fugitive hiding on an island in the Mississippi River. Two teenage boys discover him and try to reunite him with his true love, played by Witherspoon, as bounty hunters close in on him.
