Talk about a stunner! Julia Roberts hit the red carpet for the premiere of her film Money Monster during the Cannes Film Festival today, and the actress has never looked better.

InStyle's June cover star shined in a plunging black gown that featured structural off-the-shoulder sleeves, which she topped off with a dazzling Chopard emerald and diamond necklace along with diamond studs. Roberts kept her signature strawberry-hued locks down in loose waves, exuding Old Hollywood glamour. But the best part? She went sans shoes for the premiere. Surprisingly, this marks the first time the actress has ever attended the annual fest, but she seemed like an old pro. Roberts shared several laughs with old pal and co-star George Clooney as they walked the carpet and posed for photos together.

Roberts opened up about her debut appearance at Cannes in our June issue, where Editorial Director Ariel Foxman asked her why she's never been. "Have you ever watched it on television? It looks terrifying. It looks as scary as someone saying, 'OK, so this is the position that you’re going to play in the Super Bowl for 2017,'" Roberts said. "I’ve kind of avoided it. I mean, the first time I ever went to Asia was for a movie, Eat, Pray, Love. I’m a late bloomer." She also added that she was apprehensive about such a lengthy red carpet walk: "It seems like you have to walk a very long distance and then a lot of stairs."

But this isn't her first winning look of the day. This morning, Roberts attended a photo call for the movie wearing a pinstripe jumpsuit over a crisp white shirt.
