The former 'Pretty Little Liars' star and her husband Patrick J. Adams have welcomed their first child into the world, a baby girl whom they have not yet revealed the name of.

Patrick announced the news on his Instagram on Monday (08.10.18) as he posted a picture of his daughter's tiny hand holding his finger.

He captioned the snap: "The world just got 8lbs heavier. Thank you to everyone who fought for and protected our privacy during this incredible and beautiful time in our lives. Everyone is happy and healthy and loving every moment of this. I could not be more excited to bring a baby girl into this world at this moment. We will raise her to be powerful, to always speak her mind and heart and to live without fear. It's a brand new day and a brave new world and they are both beautiful."

Troian posted the same picture on her own Instagram account, and said she was determined to raise her baby girl to be "kind and strong".

She added: "I cannot express how grateful I am. To the people who have protected us and kept our growing family safe and respected our privacy. To our tribe for expanding with grace and exponential amounts of love. To my @halfadams for being so supportive during every moment of my pregnancy and her birth. And to whatever incredible force of fate that brought this baby girl into our lives. I couldn't be more proud to be her mother. To bring a new girl into this world and to do my best to raise her to be kind, strong and whatever the heck she wants to be."

Speculation of the 32-year-old actress' pregnancy began in August, though neither of the pair - who married in 2016 following a two-year engagement - ever confirmed the news.

One month earlier, 'Suits' star Patrick said he and Troian had begun discussing the idea of having a family.

The 37-year-old actor said at the time: "We talk about it all the time, obviously, and when the time is right, the time will be right. You know, we're not going anywhere. Very much in love and excited for everything that comes next."
