Viewers have known about it for a month, but Vienna Girardi says she was blindsided when Jake Pavelka showed up on the Bachelor Pad premiere.
"The producers will never tell you who's on the show, but they did say that no 'Bachelor' or 'Bachelorette' [star] would be invited," she said.
In other words, because Jake actually starred as The Bachelor, she could count on him walking through those mansion doors. So she thought.
That moment Jake arrived is still on her mind, Vienna Girardi says:
"I was absolutely terrified. The funny thing is [Jake] called me three days before filming started. I hadn't seen him in close to a year. I didn't answer the call, but I had a strange feeling it was to tell me he was on the show."
Instead of bolting, Vienna leaned heavily on her new boyfriend, Kasey Kahl, whom she's still dating - and reportedly moving in with.
Needless to say, the casting moves paid off for ABC.
