Not your average maternity dress! Pregnant Blake Lively flaunts her growing baby bump in figure-hugging blue gown at the BFG premiere in Cannes

She rarely puts a fashion foot wrong and always makes an effort for the red carpet.

But Blake Lively surpassed herself when she stepped out at the Cannes Film Festival on Saturday afternoon, where she dazzled at the annual event's latest A-list gathering.

The actress - who is expecting her second child with actor husband Ryan Reynolds, 39 - flaunted her growing baby at the Palais des Festivals' BFG premiere.

The revealing number, which was virtually strapless and featured a cleavage-enhancing neckline, was made of sequinned blue silk and featured a lengthy trail.

Snug around her form, the number - which also featured a thigh-high slit - gave onlookers a glimpse at her maternal figure.

Defying any traditional expectations around maternity wear, she added a sexy pair of strappy, silver shoes, which added height and extra glamour.

Sweeping her hair back into a high ponytail, she boasted her long locks in a smooth trail down her exposed back.

Showcasing a healthy, golden tan and some nude make-up, she was every inch the natural beauty and commanded attention in her near-regal wardrobe selection.

Possessing a keen eye for detail, she capped the look with a pair of dramatic diamond earrings.

                                            

The latest sighting comes just a few hours after she promoted her movie, The Shallows, at the French Riviera town's Majestic Beach on Friday afternoon.

Putting on a leggy display in an unusual white minidress before changing into a blue cut-out number to greet her fans, she looked fantastic.

Her first outfit consisted of a delicate oyster-coloured silk top with gold embellished detailing, the former Gossip Girl star's dress was capped off with a quirky cape with a black clasp.

Blake added height to her frame with a pair of monochrome pointed stilettos, which served to accentuate her toned and tanned legs. The mother-of-one toted a small black box clutch bag with pearl detailing and wore her flowing blonde locks swept into a chic up-do.

Although Blake is pregnant with her second child, that doesn't mean she's taking it easy at the Cannes Film Festival.

Later that day, she changed into a blue form-fitting midi dress which had cut-out sections running throughout. She teamed them with a pair of metallic green strappy sandals, wearing her blonde locks up in an elegant chignon.

On Thursday night, she made her way to the star-studded Vanity Fair bash alongside the likes of screen stars Naomi Watts, Susan Sarandon and Jessica Chastain.
