But far from being the only radiant mother-to-be on the red carpet, the 41-year-old French actress was also joined by Bond girl Lea Seydoux, who is expecting her first child.

The movie is based on the play Juste la fin du monde by Jean-Luc Lagarce, but was named by Variety as 'the most disappointing film at Cannes'.
However, The Guardian gave it four stars saying 'The claustrophobia of family has rarely been so well-wrought as in the latest highly stylised – and highly polarising – drama by the French-Canadian enfant terrible'. 
It's Only the End of the World is slated for release in the UK on April 17.

Marion announced her pregnancy under slightly less desirable circumstances, after she was dragged into the news surrounding the break-up of Angelina Jolie and Brad Pitt. 
Following rumours that she had an affair with Brad whilst working with him on Allied, the Oscar-winner took to Instagram to clear up the rumours. 
In a lengthy post, she wrote: 'This is going to be my first and only reaction to the whirlwind news that broke 24 hours ago and that I was swept up into.'

She continued: 'I am not used to commenting on things like this nor taking them seriously,' she continued, 'but as this situation is spiraling and affecting people I love, I have to speak up.
'Firstly, many years ago, I met the man of my life, father of our son and of the baby we are expecting. He is my love, my best friend, the only one that I need.'
'Secondly to those who have indicated that I am devastated, I am very well thank you. This crafted conversation isn't distressing.'
