Robin Roberts is dancing around her Manhattan living room in her bare feet, reprising her grand entrance on Dancing with the Stars—this time, without the 6-in. stilettos. Step, step, spin and dip. The 53-year-old Good Morning America anchor, who appeared as a guest judge last month, has apparently got moves. More than that, Roberts says, "I've got my mojo back!"
After facing the fight of her life against a blood and bone-marrow disease called myelodysplastic syndrome, the beloved anchor and breast cancer survivor is not only still standing, she's got a new spring in her step. Her skin is glowing, her hair is thick, and her muscular 5'10" physique, once alarmingly thin after dropping to 115 lbs., is making a comeback. Says her friend, CBS This Morning cohost Gayle King: "She looks better than she's ever looked." Even Roberts marvels at how far she's come since undergoing a bone-marrow transplant in September 2012. "I'm so much stronger now," she says.
