Hollywood's baby boom just won't stop!

On Wednesday night, Danny McBride told Conan O'Brien he and wife Gia Ruiz are expecting a son.

"I got married last October," the Eastbound & Down star explained. "I wasted zero time--three months later, I knocked my wife up." (Using McBride's math, the couple's baby should be due sometime this September.)

"I had never impregnated anyone before, so I didn't really realize what they teach you in health class is actually true--that's all it takes," the 34-year-old comedian quipped. "It's amazing."

McBride, who costarred with James Franco and mom-to-be Natalie Portman in Your Highness, revealed the sex of the baby's gender. "We've been told it's either a three-legged girl or a very well hung boy. We have either a marathon runner or a porn star!"
