Robert Irwin just brought the heat, and a whole new level of excitement to the ballroom! Article continues after this ad AdvertisementIrwin and his pro partner, Witney Carson, unleashed a steamy Salsa routine set to Tommy Richman’s hit “Million Dollar Baby.” The routine was already high-octane, but the energy spiked when Robert went full heartthrob and ripped off his black button-down shirt mid-dance. Carrie Ann Inaba perfectly captured the moment, joking, “Robert Irwin is all grown up. Wow, you’re making me feel like a grandmother!” Fellow judge Bruno Tonioli took the praise even further, comparing the young Australian to none other than Hollywood star Chris Hemsworth. Witney is reportedly acting as Robert’s “DM screener,” making sure her focus, and Robert’s, stays on the competition.
