Selma Blair is now a proud mum to son Arthur Saint.
The Hellboy actress and her fashion designer boyfriend Jason Bleick welcomed their new son on July 25.
Her spokesperson confirmed to People.com that baby Arthur weighed in at 7lbs, 12ozs.
Selma, 39, and Jason announced the pregnancy in January, when her publicist revealed: "They couldn't be happier. Her life right now is a dream come true."
The couple, who met when they collaborated on Jason's fashion line EVER, preferred to keep baby Arthur's gender under wraps until he was born.
"I'm not going to say what it is yet. Hopefully, it's one or the other," she had said.
