Blake Lively Finally Shows Off Her Baby Bump at Cannes - See Her Gorgeous Blue Gown!

Blake Lively is finally showing off her baby bump at the Cannes Film Festival!

After days of rocking absolutely amazing fashions that mostly hid her pregnancy, the 28-year-old actress put her burgeoning belly on display at the premiere of The BFG on Saturday.

Lively pulled her hair back into a tight ponytail to properly show off her one-shoulder cornflower blue Atelier Versace chiffon gown, which featured a long train, high leg slit and Swarovski crystals. She paired the stunning frock with diamond jewels and strappy Christian Louboutin heels.

The Gossip Girl alum did rock a skintight navy-and-teal cut-out cocktail dress from Versace on Friday, yet somehow, her baby bump didn't stand out quite as much in that ensemble. Perhaps it was the dark hues?
