The actor stopped by The Wendy Williams Show on Thursday and revealed that the answer is all in their personalities.
Burtka, 39, thinks that Harper Grace might be biologically his because, as he put it, “She’s like, ‘Hey everybody, I’m here!’ “
Meanwhile, Gideon Scott is likely Harris’, says Burtka, because “He’s a little more heady and intellectual.”
The twins, now 4 years old, were born via surrogate.
“It’s a lot harder for gay guys [to have kids], although we tried!” Burtka joked to Wendy Williams, going on to explain that there were “two different women involved. There was an egg donor, a wonderful woman who was anonymous. We took two of our best guys and implanted them into her eggs, two different eggs.”
And then, of course, there was the surrogate who carried the babies to term, giving birth to Gideon and Harper in October 2010.
“Gideon eats everything you put in front of him,” said Burtka. “His passion for cooking and eating good food is in his soul,” adding that his son loves “clams, sushi, octopus, grilled pork, steak, parmigiana cheese, ginger, mint, cinnamon and coconut.”
As for Harper, Burtka says she likes “briny flavors” and particularly enjoys “oysters, sardines, prosciutto, capers, duck liver, miso, and anything chocolate.”
