Bob Harper is Rach's co-host today, and he's meeting one incredible woman who was inspired to lose over 180 pounds by watching our show! Then, we're giving her a FAB makeover to match her brand-new body with the help of our friend and style pro, Gretta Monahan. Plus, actress, singer and jewelry designer Christina Milian is busting out some serious dance moves -- and dishing on her daughter's Instagram popularity, as well as her French pop star boyfriend! And why is there a six-foot unicorn in our studio?! Well, a tech expert is giving us the lowdown on summer's hottest gadgets and gizmos. And Rach is making a protein-packed breakfast-for-dinner.
