Dancing with the Stars hoofer Maksim Chmerkovskiy is denying soccer star Hope Solo’s accusation that he slapped her during rehearsals for the ABC show. Solo, who won a gold medal at the London Olympics, makes the startling claim in her new biography Solo: A Memoir of Hope. She says that during the 13^th season, Maks “manhandled me in rehearsals from the start, pushing me, whacking my stomach, bending my arms roughly.” She adds, “I thought that was just how it went – how dancers worked with each other. But it kept getting worse.”  She then claimed Maksim slapped her “hard” across the face, but was “extremely apologetic” afterwards. Solo even said there was video of the incident, which mysteriously disappeared.  Well, Maksim is denying he ever laid a hand on Solo. On Thursday he tweeted, “Always hated hypocrites and liars...but when someone is both AND an opportunist, I just feel bad for them. Can't win at someone's expense."  And Maksim’s current Dancing partner Kirstie Alley has his back. She tweeted, “I shall bite thine tongue, lest I get into a girl fight that I would surely lose without a hammer in my hand...;)... ouch! bloody tongue.”
