Leah, 25, was revealed as Lord Alan Sugar's latest business partner during a nail-biting final last week and she headed to Dublin to speak about her success.
The trained doctor, who is from Northern Ireland, was booked on Saturday Night With Miriam and posed for pictures outside the RTE studios.
Leah spent most of this year's Apprentice with her hair styled in loose curls, but Saturday (20 July) she opted for a different look.
The businesswoman's hair was plaited in an intricate fishtail braid, which was gently pulled over her left shoulder, and she kept her make-up fairly natural.
Leah, who had gone head-to-head against Luisa Zissman in the final, was also rocking a cream jumpsuit with long-sleeves. She teamed it with a silver belt and patent nude courts.
Prior to touching down on the Green Isle, Leah tweeted: "Just arrived in sunny Dublin! Very excited to be a guest on Saturday Night With Miriam live on RTE tonight."
