Description:In Olympic star Hope Solo's new book, 'Solo: A Memoir of Hope' the soccer star makes claims that her DWTS partner Maksim Chmerkovsky slapped her behind the scenes of the show when the two were partners in 2011. Sources close to Maksim tell TMZ, he has no idea why Solo would publish such a false and defamatory statement and doesn't know why she would have such ill will towards him...especially because they've had dinner several times since the show ended.(0:54)
