Clad in black jeans and a black T-shirt, the 32-year-old 'House of Lies' star rolled up to expose her bare, pregnant belly, looking radiant and relaxed, reported Us magazine.
Three days earlier, Bell celebrated her approaching due date with a group of her closest pals at a party in Los Feliz, California. "All my best girlfriends came to my baby shower," she tweeted February 23, alongside a photo of herself with 'House of Lies' co-stars Ben Schwartz and Josh Lawson.
Also in attendance at the bash were 'Hart of Dixie' actress Rachel Bilson and writer Kelly Oxford, who shared a funny snapshot of Bell posing with breast pumps. This will be the first child for the actress and her fiance, 'Parenthood' star Dax Shepard, who proposed in 2009 after two years of dating.
