ESPN reporter Erin Andrews and professional dancer Maksim Chmerkovskiy are not only paired up on Dancing With the Stars, but according to an insider, they’re secretly developing a romantic partnership as well. “They have amazing sexual chemistry,” a show insider explains. “She is totally his type, and he is totally the type of guy that she falls for.” While Erin, 31, and Maks, 30, have only hinted about their love connection, the insider reveals that they started seeing each other from almost the first week of rehearsals — and they were always the first to arrive and the last to leave. “Maks really likes to cook Russian food, and he’s been cooking for Erin,” the insider continues. “They’re both relationship-driven, so this is likely to be much more than just a fling.” Maks has been helping with Erin’s footwork — and an insider says she has also been leaning on him to cope with reported death threats.
