Maternity style had a monumental moment yesterday, when a trio of Hollywood's most stylish—and pregnant—starlets stepped out for three flawless appearances.

Kristen Bell stopped by the Los Angeles premiere of The Judge, in a clingy LBD with a crisscrossed halterneck (above, left). The actress, who is expecting baby No. 2 with husband Dax Shepard, has maintained her red-carpet A-game throughout her pregnancy, from dressing in a brightly colored floral Wayf dress to sparkling in an airy white Elizabeth and James dress and rocking jumpsuit-like Etro separates.

Mom-to-be Zoe Saldana pulled out all the stops to attend the opening for the "Hollywood Costume" exhibit in L.A. She donned a pink cashmere Dior gown and accessorized with open-toed Louboutin heels and a fuchsia Dior clutch (above, center). Husband Marco Perego accompanied her on the red carpet and the couple looked picture perfect.

Meanwhile, across the Atlantic, Liv Tyler dressed in head-to-toe Miu Miu (above, right) to attend the brand's spring 2015 Paris Fashion Week show. The actress is expecting a child with partner David Gardner, a sports and entertainment agent. The new baby will be a sibling to Tyler's son from a previous marriage, 9-year-old Milo Langdon.

Could the three expectant mothers have looked any more radiant? We think it's virtually impossible!
