Selma Blair, her beau Jason Bleick and newborn son Arthur Saint Bleick took a walk through Hollywood together on Saturday.

Just two weeks after Arthur's birth, Blair, 39, was all smiles in a sleeveless patterned dress.

"I feel like the luckiest girl in the world," the actress told Us Weekly at her June baby shower, hosted by BFFs Sarah Michelle Gellar, Jaime King, Karen Zambos and Janey Lopaty. 

Blair -- who ended her two-year marriage to Ahmet Zappa in 2006 and dated her Kath & Kim costar Mikey Day from 2008 until 2010 -- announced her pregnancy in January.
