It seems like only six months ago that Julia Roberts finally admitted to being "knocked up" for the second time in approximately two years. (Wait a second, it was!) Which explains why today, People's already announced the arrival of the third—and newest—member of the Roberts-Moder, a boy named Henry Daniel, who weighs in at an impressive 8.5 pounds.

Henry was born Monday in Los Angeles and weighed 8½ lbs. "The Moder family is doing great," Roberts's rep, Marcy Engelman, tells PEOPLE exclusively.

Meanwhile, Henry's older brothers, two year-old twin terrors Hazel and Phinnaues, are said to be incredibly excited about their brand new younger brother, but annoyed by his "disappointingly unpretentious first name."
