Selma Blair on Baby Arthur: "He's Perfect"

OK! caught up with Selma Blair backstage at the J. Mendel show for NYC Fashion Week on Wednesday where the Dark Horse actress opened up about her and boyfriend Jason Bleick's seven-week old son, Arthur Saint.

"He's perfect," Selma told OK!. "Arthur is perfection. He's as good as a newborn can be."

Selma, who gave birth on July 25, is definitely finding ways to balance her new role as mother with her career.

"He came to Venice for the Film Festival and to Toronto, and right here and he's been a captain all the way. He's been amazing."

And the jet-setting lifestyle doesn't seem to bother Arthur one bit! When asked if he had any great milestones yet, Selma replied:

"He's been smiling since two weeks. He already weighs 13 pounds. He's very tall, at seven weeks. And he's… the smiling is the biggest one."

It seems as though Selma, Arthur and Jason are one big happy — and smiling—  family!
