Yep ... it happened.
Kirstie Alley had to pick herself up off the ground last night after Maksim Chmerkovskiy suffered a "charlie horse" type pain that made his leg give out.
Kirstie eventually forgave Maksim -- tweeting after the show, "I salute u... U r a gladiator .... A champion... I'm honored to be your partner."
