There's a new little one in the Biggs household!

"American Pie" actor Jason Biggs and his wife, actress Jenny Mollen, announced the birth of son Sid via Instagram on Tuesday.

"Sid Biggs," reads the caption on a full-face shot of the little guy in his Cedars-Sinai Medical Center crib. "Full head of hair, huge penis, 10k twitter followers."

The baby was born at 5:33 p.m. Saturday, weighing in at 8 pounds, 8 ounces, and measuring 21¼ inches long.

Mollen also posted a series of short videos of her trip to the hospital ("It hurts so bad," she says), her epidural and more, including a selfie-style clip after the delivery in which Biggs tells his wife: "You did amazing, sweetie, I'm so proud of you. So proud of you. He's beautiful."

"Is he cute?" she asks.

"He's pretty damned cute," the new dad replies.

The two got married in "a very private ceremony" in April 2008, after meeting on the set of "My Best Friend's Girl."
