Penn Badgley and Domino Kirke are saying hey, you to life as parents of four. 

The You star and his wife of eight years have welcomed twin boys, he confirmed Sept. 3. 

Penn gave a glimpse at their tiny feet in an Instagram video, saying, “I’m whispering… I don’t want to wake them up.”

He explained that he’s been on parental leave after the babies’ arrival but is returning to the spotlight to promote his book of essays, Crushmore, out Oct. 14.

“Interrupting twin paternity leave to announce a live event @podcrushed at @symphonyspace Oct 14 NYC supporting the release of our book CRUSHMORE,” he wrote on Instagram. “Truly proud of this one. Please check it out!”

The two little ones join the couple’s 4-year-old son, as well 16-year-old Cassius from Domino’s previous relationship with Morgan O’Kane. But while Penn and Domino are well practiced in parenting boys, , the singer previously revealed how she thinks it’ll be different this time around.
