James Van Der Beek, the former star of Dawson's Creek, and his wife Kimberly welcomed a daughter, Olivia, on Saturday. And the actor, 33, is already gushing with emotion.
"Had the blessing of becoming a father over the weekend... Couldn't come close to describing this bliss even if I had 140 million characters," he wrote on Twitter.
Adds the actor: "Olivia Van Der Beek, born 9/25. I apologize in advance for any obnoxiously precious new-dad tweets that may follow. I'm under her spell."
Baby girl weighed in at 7 lbs., 2 oz and is 19.5 inches long, the proud papa tells PEOPLE.
The Van Der Beeks were married in August. "Best day of my life so far," he Tweeted at the time – although perhaps that's now been eclipsed by the new arrival.
