WATCH: Kirstie Alley's New 'Dancing with the Stars' Partner?

ET's Mark Steines cut in on Kirstie Alley's "Dancing with the Stars" pro partner Maksim Chmerkovskiy, performing a few steps of the samba with the actress.

"You're in Brazil," Kirstie exclaimed, impressed by Mark's dancing prowess.

Kirstie was also impressive, learning the samba faster than any other dance, which will come in handy since this week the remaining ballroom warriors will perform at least three dances.

Now, that Kirstie has reached the finals, she said "it feels like my dreams are coming true."

"I know you want to hear, 'Oh no. Oh my God, I had no idea I would ever be here,'" said Kirstie. "[But] I so wanted to be here that that's just the way I said it was going to go."
