Mom-to-be Emily Blunt is expecting her second child with hubby John Krasinski, and her friend Charlize Theron is helping the actress get ready for the new bundle of joy by throwing the sweetest star-studded baby shower.

On Sunday Theron, 40, who starred alongside Blunt in The Huntsman: Winter's War, welcomed guests such as Theron's mother Gerda Martiz, fitness trainer AJ Johnson, makeup artist Jenn Streicher, and stylist Laini Reeves to the exclusive bash. Blunt, who is already a mom to 2-year-old Hazel, definitely had that pregnancy glow and arrived at the shower dressed for warm weather in a flowing blue-and-white printed maxi dress, sandals, a light blue denim jacket, and tortoiseshell sunglasses.

Johnson documented the event with a fun group photo (below) on her Instagram account. "More #Sundayfunday hangin with these super heroes-the REAL avengers @jennstreicher @laini_reeves @Charlizeafrica #charlisetheron," she wrote in the caption. In the snap, Blunt wears a festive headpiece while sitting in front of a baby-blue cake decorated with rubber ducks.
