How to Get Away with Murder star Karla Souza and her husband Marshall Trenkmann have had their second baby! Their son was born on Friday, June 12th.

Together with a PEOPLE exclusive, Souza shared the news of her son’s arrival on Instagram along with his name: Luka Olivares. She wrote, “Thank you @people for helping me share our joy with the world. There’s so much heaviness and injustice in the world and as a mother it makes me wonder what world my children are growing up into. Looking into Luka’s eyes and watching Gianna as a big sister brings me so much hope and commitment to being a part of the change. Welcome to the world Luka.”

Luka is Souza and Trenkmann’s second child and he joins two-year old sister Gianna. Her pregnancy was announced in May when she posted a photo featuring her daughter, her baby bump, and shirts for the both of them saying “Mama Bird” and “Little Bird”.

Souza and Trenkmann, a banker, tied the knot in 2014.

Congratulations to Karla, Marshall, and Gianna!
