Reese Witherspoon was the pregnant belle of the ball at the Cannes Film Festival Saturday.
For the premiere of her new film, Mud, Reese stole the show from the film's star Matthew McConaughey -- Witherspoon has a small supporting role -- in a stunning low cut indigo gown, accented by some major diamond bling.
Earlier in the day, for the press photo call, she wore a form-fitting black Versace dress with fuchsia stilettos.
Reese and husband Jim Toth, who accompanied her to Cannes, are expecting their first child.
She has two older children with ex-husband Ryan Phillippe.
Reese is staying in top shape through her pregnancy.
As RadarOnline.com recently reported, she is still playing tennis and going on hikes.
