Evan Rachel Wood had given birth to a baby boy.
The Associated Press cited Woods' representative as saying the 25-year-old actor, married to Briton Jamie Bell, "and baby are all doing well."
Wood is known for her role in HBO's "True Blood," and her film credits include "The Wrestler" and ''Thirteen."
She earned Golden Globe and Emmy nominations for her supporting role in "Mildred Pierce."
Bell, 27, is best known for his roles in the films "Billy Elliot," ''Jumper" and "The Adventures of Tintin."
The couple announced the pregnancy in January after tying the knot in front of family and friends the previous October, People wrote.
Wood recently took to Twitter to make this plea to her 170,800 followers:
I believe kids should be protected and not public domain. When my baby comes I would greatly appreciate no support of any pap photos. It starts with you. Big thanks to anyone who understands and shows their support. Lots of love.— Evan Rachel Wood (@evanrachelwood) July 21, 2013
She struck a lighter note earlier in the pregnancy, the ABC wrote, tweeting:
"I can’t wait for my own Littlefoot to get here!" and including a link the film "The Land Before Time."
