Penn Badgley knows the many ways that one can be a parent.

The You star, who is married to singer Domino Kirke, shares a 15-year-old stepson, Cassius, with his wife. The couple also have a young son of their own.

Badgley opened up about parenting both in a candid episode of The New York Times Modern Love podcast , which was released Wednesday.

I have an interesting situation where I have a biological son and a stepson, the Gossip Girl actor said. And my stepson is his father is very much in his life, so his father is his father, and Im Im something else. So I have two different parental roles.

And then my biological son is only 3 1/2, so thats a very different thing too. Im going to need to be able to more consciously show him my vulnerability as he gets older in those years.
