The action star and his wife, model Emma Heming-Willis, welcomed a daughter on Monday. Evelyn Penn Willis weighed 8 pounds and 10 ounces. She joins older sister Mabel Ray, 2.
"Both mother and baby are healthy and doing beautifully," his rep said in a statement. "Mabel is delighted to have a new baby sister."
Willis next appears in Sin City: A Dame to Kill, which hits theaters in August. Check out the episode of Saturday Night Live when he last hosted here.
