About a month before Decker spent weeks traveling through Fiji, Tahiti and New Zealand in a tiny RV with five castmates last February, she was the Playboy Cyber Girl of the Month. The magazine originally discovered her for its 2002 Girls of the Big 12 pictorial.
The 12th season of Road Rules began airing on MTV this week.
Decker said she told the show's producers about her deal with Playboy (search) early on. "It was mentioned a little bit here and there but not too much," she said. She also talked about it on the air during the season premier this week.
On the show, the cast spend lives together in close quarters while completing a series of intense, extreme challenges and traveling hundreds of miles.
At the beginning of the game they give up all their cash and credit cards and are given maps, a GPS (global positioning satellite) receiver and just enough money to help them get through each part of their trip.
They compete for a mysterious "handsome reward."
