What Happens When Pregnant Marion Cotillard Meets Mom-To-Be Lea Seydoux? Find Out Here.

Marion Cotillard and Lea Seydoux at the red carpet last Friday for the BFI Film Festival in London

Bumping their baby bumps together, Marion Cotillard and Lea Seydoux joined together on the red carpet last Friday at the BFI Film Festival in London. The two soon-to-be mothers seemed to be getting along and sharing a pre-maternal bond side by side, as they hugged and laughed in front of cameras and appeared for the event.

While it was pretty nice to see both the mothers happy together, it was also a treat to the eyes and lessons for the mind to pick up tricks on how to dress when you are expecting a baby.

Barely showing off a bump, Marion Cotillard poses for the cameras in front.

The Allied actress came in wearing a a black, ankle-length dress which showed off her shaped shoulders. Her dress had a haulter neckline and was moderately glitzy and glam because of the random gold chunks. Her dress ended just at the right length to show off her pencil heeled shoes.

She kept her accessories simple by only carrying a chained bracelet on her wrist and a ring.

While Marion Cotillard's baby bump was barely visible in her tulle dress, our favorite Bond girl Lea Seydoux's bump was all out in her cobalt blue gown. Her cape-like sleeves and a-line skirt gave the finesse that the dress frankly needed.

It seemed like the mommies had an agreement earlier regarding their accessories as Seydoux had also kept her ornaments to a minimum by just wearing a diamond drop-down earring.

Bump so big you could call it Bumpzilla

The synchronization did not stop there. Both of these glowy, beautiful women were seen sporting a very natural look.

Lea Seydoux wore a plain face with a hint of natural blush and baby pink lips. She also gave an orange contouring that flattered her skin tone with the blue dress. She kept her golden tresses open, sporting a wavy hairdo. Her painted nails in the color burgundy went along with the entire look.

Lea announced her pregnancy with boyfriend Andre Meyer just last month and showed it off for the very first time at the Toronto Film Festival.

Marion also seemed to keep her make-up simple with nude lips, warm toned eyes and a light stroke of blush. Her hair was loosely pulled back with a puff on her crown.

Pst, one secret though: her dress is from Christian Dior's Fall Couture 2016 Collection.
