Ricki Lake seems to already be fully embracing her upcoming appearance on Dancing With the Stars
– and battling nerves at the same time.
In a new video posted on YouTube
, the actress and former talk show host – wearing a tutu – gamely admits, "I'm more than a little nervous. I'm actually terrified."
The newly engaged
Lake, 42, encouraged fans to send her dancing pointers via Twitter
, insisting her starring role as Tracy Turnblad in the original film version of Hairspray
back in 1988 does not put her at an advantage.
"I was faking it," she said of the role. "I am not a trained dancer. I have no idea what I'm doing."
She also gives a shout-out to former contestant Kirstie Alley
"She was a big inspiration for me last season," Lake said. "I'm hoping I do half as well as she did."
Added Lake: "I'm really excited and I can't wait to start."
The season 13 lineup
also includes Chaz Bono, Nancy Grace, Kristin Cavallari, David Arquette and more.
