Marion Cotillard and partner Guillaume Canet welcome a baby girl

Marion Cotillard and her long-term partner Guillaume Canet have a very special reason to celebrate, the pair have announced the birth of their second child!

A rep for the Hollywood couple confirmed exclusively to People magazine that the pair have become parents for the second time.

Limited details were given, with the rep mysteriously saying the birth had happened ‘recently’. Although they did reveal that Marion and Guillaume now have a baby girl, there was no mention of baby names at this stage.

The acting couple’s newborn baby girl will be a lovely little sister for the five-year-old son that the couple already share, named Marcel.

Marion, who is not only a French actress but singer, songwriter and musician as well, originally announced her pregnancy back in September.

The 41-year-old took to Instagram to delight fans with the sweet news, writing a lengthy caption which described her long-term partner as ‘my love, my best friend, the only one I need’.

At the time she said of her pregnancy, ‘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.’

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. I am not used to commenting on things like this nor taking them seriously 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. And to all the media and the haters who are quick to pass judgment, I sincerely wish you a swift recovery. Finally, I do very much wish that Angelina and Brad, both whom I deeply respect, will find peace in this very tumultuous moment. With all my love Marion Ceci sera la première et seule réaction que j'aurai concernant la déferlante inouïe qui à commencé il y a de ça 24 heures et à laquelle je suis mêlée malgré moi. Je n'ai pas pour habitude de commenter ni de prendre au sérieux le tas d'absurdités déversées à mon sujet mais la situation prenant une telle tournure et affectant des gens que j'aime, je me dois de m'exprimer. Pour commencer, j'ai rencontré il y a quelques années l'homme de ma vie , le père de notre fils et du bébé que nous attendons aujourd'hui. Il est mon amour, mon meilleur ami et le seul homme dont j'ai besoin. Ensuite, à ceux qui me prétendent dévastée, je vais très bien merci. Ce genre d'inventions aberrantes ne m'affecte en aucun cas. Et pour finir, à la "presse", à tous les haters, trolls et consorts qui ont le jugement si rapide je vous souhaite sincèrement… un prompt rétablissement. Ceci dit et un peu plus sérieusement, je souhaite à Angelina et Brad, deux personnes pour qui j'ai un profond respect, de trouver la paix dans ce moment tumultueux. Avec tout mon amour. Marion

The couple were last seen out together in February for the premiere of their latest film Rock’N Roll, which was directed by Guillaume and romantically stars them both.

This will be the third film that the parent team will have appeared in together, the second being 2009’s The Last Flight.

Marion and Guillaume first began dating a decade ago when they met on the set of film Love Me If You Dare. This was their first experience acting together, and clearly it went very well!

Congratulations to the lovely couple!
