Alyson Hannigan is revealing her thoughts after making it into the Dancing with the Stars finale.

Speaking exclusively to PEOPLE on Tuesday at week 10’s DWTS semifinals, the actress revealed her surprise when she and dance partner Sasha Farber were announced as having made it to the finals.

“I thought Alfonso [Ribeiro] made a mistake,” Hannigan, 49, tells PEOPLE of the show's co-host. “I thought he meant to say Ariana [Madix] and he said my name first and I just was waiting for him to correct himself and then I couldn't believe it."

"I was totally shocked," she adds.
