(Cover) - EN Showbiz - Selma Blair showed off her svelte post baby body last night just five weeks after giving birth.

The 39-year-old actress made her red carpet debut for the first time since having her baby boy Arthur Saint.

She looked amazing in a fitted green Roland Mouret dress and showed little sign of any post-pregnancy weight.

Selma later attended the premiere for her new film Dark Horse which is about a thirty-something man who lives with his parents but ends up falling in love for an equally immature thirty-something woman.

The proud new mother brought her bundle of joy on the trip to Italy with her and was seen giving Arthur lots of cuddles at a local restaurant.

Her fashion designer boyfriend Jason Bleick stayed at home but Selma posted a message on her Twitter page just before her journey.

"Off to Venice for Dark Horse with Baby Saint," she tweeted. "St. Christopher protect us. Daddy, we will see you back home soon. Love. SB." (C) Cover Media
