Kourtney Kardashian is no stranger to glam maternity style.

So it’s no surprise the reality TV star was on hand to help author Amy Tara Koch (above left) celebrate the launch of her maternity fashion guide, Bump It Up, at the W South Beach Hotel in Miami, FL on April 1.

Miami’s most stylish moms and moms-to-be dined on mini baby-themed cupcakes and enjoyed hand massages and facials from Bliss Spa while listening to Koch share her top pregnancy style tips.

Kardashian also came out to debut her limited-edition design for Belly Bandit ($66). The new mom — who’s in town filming a new season of E!’s Kourtney & Khloé Take Miami — credits the belly wrap with helping her quickly get back into bikini shape. Other celeb fans include Minnie Driver, Julie Bowen and Ana Ortiz.
