Kristin Chenoweth Recalls Her Gleek Roots On ‘When I Was 17′

'I was the popular geeky girl,' she says on Saturday's episode.

During Kristin Chenoweth’s high school days, life was like an episode of “Glee.” She was the real-life Brittany, chilling with the resident gleeks at her high school and also getting her groove on at football games.

So it makes sense that Chenoweth would grow up to be not only a Broadway star (including stints in “Wicked” and “Promises, Promises”), but also make cameos on the hit Fox musical series. On this week’s episode of “When I Was 17,” which also features appearances by Jay Sean and Soulja Boy Tell’em, Chenoweth reveals that she existed somewhere in the middle of her school’s popularity totem pole.

“I was the popular geeky girl,” she says on the show, which airs Saturday at 11 a.m.

So what kind of after-school activities does the school’s resident “popular geeky girl” find herself doing? “I had friends that were, like, in the smoke hole, and I had friends that were in the choir with me,” she says. “But I was also a Tigette, which was a pompom girl [for the school's team the Tigers].”

These days, Chenoweth is known for her upbeat demeanor, and it seems that was also the case back in high school. “[She was] like a little pixie, very quirky,” her high school principal, Max, says. “She always had a smile on her face and was friendly with everybody.”

Another thing that hasn’t changed is the entertainer’s flair for all things stylish and trendy. Back in the day, her style icon was none other than the frontwoman of the Go-Go’s. “When I was 17, I looked like Belinda Carlisle,” she said. “I had her exact haircut. I wore big earrings. I wore a lace bow in my hair tied to the side at all times.”

“When I Was 17″ — this week featuring Chenoweth, Soulja Boy Tell ‘Em and Jay Sean — premieres Saturday at 11 a.m. on MTV.
