Kirstie Alley's 'Dancing With The Stars' Quickstep & Makeout With Maksim Chmerkovskiy (VIDEO)

Kirstie Alley wowed the judges with her cha-cha on DWTS's season premiere last week, and Monday night she struggled a bit with the quickstep.

"I feel mediocre," Kirstie, 60, told E! News. "I'm telling you the truth. I know what steps I missed, I know what I screwed up on, so...that's all. I wasn't as tired [as I was last week], the stamina's gone up a bit, but this dance is hard! Who the hell walks around like this? Nobody walks like this!"

The actress and partner Maksim Chmerkovskiy received a respectable score of 20 for their routine, which ended with a dip and passionate make out.

Kirstie insisted to host Brooke Burke that the kiss was unplanned.

"It was spontaneous," she said. "I wasn't gonna do it!"

Get ready for another memorable performance next week.

"Next week Rumba... Better be hot or I'll stab myself in the vag," Kirstie tweeted late Monday night.
