Patrick J. Adams, Troian Bellisario welcome 1st child

'It's a brand new world' for former 'Suits' star Patrick J. Adams and 'Pretty Little Liars' alum Troian Bellisario, as the couple has welcomed their first child together.

The new parents took to their respective social media handles to announce the birth of a baby girl.

"The world just got 8lbs heavier," wrote Adams, alongside a picture of his wife's and the newborn's hand. "Thank you to everyone who fought for and protected our privacy during this incredible and beautiful time in our lives," added the 37-year-old.

"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," he concluded.

The new mom also shared the same picture coupled with an endearing post. "I cannot express how grateful I am," Bellisario wrote on Instagram. "To the people who protected us and kept our growing family safe and respected our privacy... 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 int our lives."

She continued: "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."

Troian and Patrick, who tied the knot in December 2016, never officially confirmed that they were expecting a child.
