(Cover) - EN Showbiz - Selma Blair has admitted that she has not lost much of her post-baby pounds.

The 39-year-old has been promoting her latest film Dark Horse around the world and has looked fabulous but she says that she really hasn't shed any pounds since giving birth seven weeks ago.

Selma gave birth to her son Arthur Saint Bleick in July but insists that she is the weight she was when she left the hospital.

"I actually haven't lost any weight since the day I left the hospital," she told Us Weekly.

"I still weigh the exact same number. I haven't really been focusing on that at all, because I've been running around to different things.

But she revealed that she has been following a regime to keep in good shape.

"I've been following Alicia Silverstone's The Kind Diet," Selma shared. "It helps with my clarity and endurance. In a few weeks I think I'll start getting into [the gym] when things slow down a bit it'll be Pilates in L.A.!"

Selma gushed about her little one saying that he is simply "perfect" and she has been showing off pictures of him on her iPhone.

"Arthur is perfection," the new mother said. "He's as good as a newborn can be."

Speaking backstage at the J. Mendel show for New York Fashion Week, Selma told OK! Magazine that Arthur is already enjoying the jet-setting lifestyle.

"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," Selma shared of her first child with boyfriend Jason Bleick.

"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." (C) Cover Media
