Annie and Nick talk beauty techniques and trends with Kim Kardashian West's makeup artist Mario Dedivanovic aka @makeupbymario. They chat about his personal and professional development, his wildly successful Master Class, why he always starts with the eyes, and of course, his new makeup collection, Makeup by Mario (out now at Sephora). Plus, Annie and Nick explore the...chewy science behind gummy vitamins, Selena Gomez's #StigmaFree pledge, and shout-out the only concealer brush Annie will shell out $40 for.
