More recently she has worked as a sportscaster for ESPN. She will compete with fan-favorite pro dancer Val Chmerkovskiy.
"This means everything," she said. "It's a dream come true, and it's something I always wanted to do but never really knew if I was ever going to have that chance, just given circumstances and everything. I can honestly say, though, that learning to walk was easier than learning to ballroom dance."
