Kaley Cuoco apparently got cold vibes from co-star Rose McGowan when the future “Big Bang Theory” star joined the 2005-06 cast of “Charmed.” (Watch the video below.)

Cuoco spilled the tea on a recent episode of Dax Shepard’s “Armchair Expert” podcast.

“I still don’t know if she liked me,” Cuoco said.

Shepard noted how “dicey” it must have been to join a show several years into its run.

The actor, who played young witch Billie Jenkins, recalled her first day on the supernatural drama, when she met her new co-stars and took photos with them in an all-day shoot.
