Forget Rozlyn's supposed hookup with a producer and Michelle getting the heave-ho: we haven't seen nothin' yet on this season of The Bachelor!

Star Jake Pavelka says the romantic reality competition is just getting warmed up this season. The lowest point "is yet to come," the single stud tells ET. "It won't be any secret," he adds cryptically.

"Horrible. Awful. On a scale of one to 10, it nears a 10." Pavelka admits that the to-be-revealed event created "devastation" for him. "It is juicy now," he teases. "It is going to get a lot juicier."

The new reality star claims that he bears no ill will toward Rozlyn nor Michelle, who left the show under less than ideal circumstances. Of Rozlyn's alleged affair with a show producer, he offers, "If she truly found love, then I'm happy for her."

What about Michelle? "Great girl. Maybe a little over emotional. She was there for me, not anybody else. She didn't care what anybody else thought. I respected that ... I felt in the end, her emotions maybe got in the way of us developing a relationship."

Pavelka poo-poos rumors that he's already engaged. "My parents don't know," he scoffs.  "They don't have any idea of the outcome, so it is amusing to think that there are people out there who do."
