Jake Pavelka, Vienna Girardi

The Bachelor Pad premiere is going to be a whopping three hours, host Chris Harrison tells TVGuide.com.

"I would never say this about any TV show because I honestly don't think any TV show deserves to be three hours, but I don't even know if three hours is enough for Bachelor Pad," Harrison says. "ABC looked at the footage and can't believe it ... That just goes to show you how good and mind-blowing it's going to be."

During Monday night's episode of The Bachelorette, viewers got a first look at the upcoming Bachelor Pad season (which debuts Monday, Aug. 8 at 8/7c on ABC) and the drama that unfolds between former flames Jake Pavelka and Vienna Girardi.

"That was just the tip of the iceberg. The whole Jake and Vienna thing is enough of a show, but that's barely anything that's going on in the house," Harrison says. "We haven't even gotten into [formerly engaged] Michael [Stagliano] and Holly [Durst]. And [Justin] Rated R the wrestler, he has the best entrance of anybody!"

And now that the final cast member has been revealed as Ames, Harrison says he'll be the breakout star of the show.  "If you loved the way he was on Bachelorette, you'll love him even more. He's even more fascinating and intriguing on Bachelor Pad," he says. "I think Ames is going to steal a few more hearts."
