James Van Der Beek and Heather BrookJames Van Der Beek is one proud new papa!

The actor announced the birth of his daughter with wife Kimberly Brook. "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 tweeted.

In another message, Van Der Beek wrote, "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..."

True to his word, his next tweet was about his newborn. "If I watch football w/ my daughter now, she'll like the sounds of the NFL & want to watch it w/ me when she's older."
