Spice Girl Melanie C and Ronan Keating joined us on St. Patrick's Day and immediately got into a debate about whether they're called "slides" or "sliders" (UK says sliders, we called them idiots, Americans call them flip-flops, and Aussies call them thongs which confused everyone). Ronan revealed his breakfast radio survival trick was plunging his face in a bowl of ice water every morning at 5am because seven years of early mornings made him look 60, Melanie's touring Australia for the first time as a solo artist in November hitting the Enmore Theatre, and Ricki had a full fangirl meltdown admitting she learned every Spice Girls dance move from the Live in Istanbul concert.
