Another boy! Rosamund Pike and her longtime boyfriend Robie Uniacke welcomed their second child together, another son, on Tuesday, Dec. 2, her rep confirms to Us Weekly.

The Gone Girl star, who gave birth at home, is already mom to 2-year-old son Solo. Us Weekly revealed the British actress, 35, was expecting this past June.

In a 2012 interview with Vogue, the star explained why she’s yet to marry her researcher boyfriend, 54. “You try to do the right thing and the conventional thing, and it doesn’t work, and then you’re free again,” she said, in reference to her past engagement to director Joe Wright. “It is interesting to break all the rules. I’m not married, I have a baby, and it feels infinitely more right.”
