Andi Dorfman has yet to deliver the final rose on this season of "The Bachelorette," but she's batting down rumors that she is already pregnant.

"That's news to me and my body!" Dorfman joked to E! News backstage at the taping of the "Men Tell All" special which aired Monday night.

"It's funny. I joke about it. It's so far from the truth, you gotta laugh," she said. "I remember saying, 'Alright, this is as close as I'll get to Kate Middleton!' Which is on the cover of a magazine. I'm like, that's totally false, but that's OK because I'm next to Kate!"

Turns out, there's an upside to the pregnancy rumors.

"It's gym motivation!" Dorfman told E! "I'll just stay in shape, then they can never say that I'm pregnant."

Dorfman makes her final choice between the two remaining men, Josh M. and Nick V., on next Monday's finale.
