Yolanda takes the girls to see Broadway show Kinky Boots hoping that the message of the show: 'to be confident in who you are', rubs off on the girls ahead of this week's challenge, which is walking the runway for Dutch designer Georgine. The guys from Kinky Boots give the models a masterclass on how to walk, and Yolanda brings in Top Supermodel Alek Wek to give the models one last confidence boost before their big day. And the model moms begin to feel the pressure as they question whether Yolanda is playing favorites.
