Ashley Grahamis having a boy!

The soon-to-be first-time mother (who is expecting her first child with husbandJustin Ervinin January) sat down withEllen DeGeneresfor a version of “Lightning Round” — a game that Graham plays on her podcast,Pretty Big Deal— when she dropped the big news.

While Graham is usually the one asking questions during the game, DeGeneres switched things up and put her guest in the hot seat. And while she didn’taddress the model’s pregnancy inthe first few rounds — starting with silly questions like, “Besides your husband, who do you have a crush on?” and “Most embarrassing wardrobe malfunction?” — in the final seconds, DeGeneres asked slyly, “Are you having a boy or a girl?”

“I’m having a boy!” Graham screamed, nearly jumping out of her seat. “I’m gonna be a mommy to a boy!”
