The mother-of-one stopped by the Good Morning America TV studios in New York yesterday (9 October) sporting a tiny pair of black shorts.
Katie added a chic white blouse and a khaki jacket, both from her own fashion label Holmes & Yang.
She spruced up her otherwise simple outfit with cute heart print tights and towering patent courts.
Her glossy chocolate tresses were styled in loose curls and she sported minimal make-up, applying a touch of pink blusher and rosy lipgloss.
While on the show, Katie spoke about her new collaboration with cosmetic giant Bobbi Brown, aptly named the Bobbi & Kate make-up collection.
The range includes a limited edition palette, £50, which boasts eight eyeshadows, two cream blushers and an eyeliner, plus a mini make-up brush set, £45.
