'My Big Fat American Gypsy Wedding' premiere sneak peek

It's a pretty strict rule for Romanichal Gypsies that there's no sex before marriage. But the community takes it even further -- there's not even any sex education before marriage. That's why 17-year-old "My Big Fat American Gypsy Wedding" subject Shyanne is completely in the dark about how things work in that department, and she won't find out until her wedding night -- which is soon, since she's engaged to 18-year-old Michael.

In Zap2it's exclusive clip of the series premiere, Shyanne talks nervously about the consummation of her upcoming marriage. "Romany girls aren't supposed to know anything about that until after they're married, and what they do learn is supposed to come from their husband on their wedding night," she says.

"If she's teaching you something, usually you didn't get the good one," laughs Michael, her fiance.

Check out Zap2it's exclusive clip from the series premiere below. "My Big Fat American Gypsy Wedding" premieres Sunday, April 29 at 10 p.m. on TLC.
