Maksim Chmerkovskiy HATES Hope Solo -- and is now blasting his former "Dancing with the Stars" partner as a "sh**ty person" and a liar who made his life a living hell.
Maksim and Hope were partners on the show back in 2011 -- and left on horrible terms ... with Solo later making claims in her book that M.C. slapped her in the face during rehearsals.
But moments ago, Maksim fired back on "Allegedly" -- a podcast hosted by Theo Von and Matthew Cole Weiss -- in which he denies the allegations and rips into the Team USA soccer star.
"She's just a sh**ty person," Maksim says. "You can have a sh**ty life growing up ... but if you're a bad person, there's no excuse for that."
Check out the clip -- Chmerkovskiy was asked to play a round of "F, Marry, Kill" ... and spoiler alert, Hope ain't gettin' a diamond ring from Maks anytime soon.
