Circumstance: Mainstream actress and wrestler turned adult film star

Spoiler alert: Wrestling is fake. If that rocks your world, sorry, but you had it coming. Chyna was one of the most popular female wrestlers of the late '90s, and landed on the cover of Playboy twice. No, really, she did. Post wrestling, she and wrestler Sean "X-Pac" Waltman sold a sex tape to Vivid, which was released as One Night in China. Her 2011 feature Backdoor to China was a true adult film, filmed with Vivid professionals like Mick Blue and Evan Stone.
