Kirstie Alley nervous about DWTS!

Kirstie Alley is freaking out!

The actress is said to be so terrified of taking to the ballroom floor Monday evening for the premiere of Dancing With the Stars that some insiders are worried she might be too scared to actually dance.

“You have no idea how nerve-wracking that first dance can be in front of a live audience in the ballroom, the judges and millions of viewers that are watching from home,” an insider told thePopEater website.

“Rehearsals help you make all the right moves, but dancing on an empty stage and blocking out your routine with the cameras is very different from going live.

“In practice she has been amazing and is a front-runner.

“I know we made the mistake of thinking David Hasselhoff was a front-runner last season oops! but the amount of curiosity over Kirstie and the amount of work she is putting into doing this means she could go all the way.”

Sources recently revealed Alley decided to sign up for Dancing With the Stars because she wanted to do it before it’s “too late”.

“She wasn’t ready last season. Mentally and physically she just couldn’t get her head around doing the show,” an insider said.

“Kirstie just turned 60, so I think she decided to take on her fear before it was too late.

“Kirstie is in this to win this.

“Don’t think for one second that she entered the competition to be voted out in the first few weeks. She’s determined to make it to the end even if it means getting her friendsJohn Travolta or Tom Cruise to show her some moves. And I guarantee no one in the history of the competition will have better friends in the audience cheering her on. Oprah, anyone?”
