The Bachelor's Jake Pavelka wanted to know what love is -- and Vienna Girardi showed him.

Although Girardi has been accused by other Bachelorettes of "shaking her boobs" at Pavelka to win his heart, the Bachelor in question says it was a chaste "45-minute conversation" about love that won him over.

During the couple's Thursday appearance on The Ellen Degeneres Show, Pavelka explains that "there wasn't any single moment" in which he knew she was "The One." "Your heart just starts to fall, but when it really turned around was when we were in Napa Valley."

DeGeneres knows that episode as well as any Bachelor fan. "When [Vienna] snuck down and got in bed with you?"

"No, before that," Girardi explains.

Pavelka says that he and Girardi had a heart-to-heart on a bench during their wine-country getaway (during a combined date with eliminated contestant Gia Allemand). "[Vienna] described what she thought of love."

"This was in the courtyard. This wasn't in the bed," Girardi , 23, reiterates.

"The bedtime was later," Pavelka says. During the chat, the 32-year-old pilot was struck by her  "values and spirituality and different things like that...I just realized 'wow, we really line up.'"

The controversial pair are avid watchers of their show, too. "We've watched almost every episode together," Girardi says. "We haven't watched the finale yet because we haven't had a chance to. We lived it -- we know what happened!"

The smitten twosome have also been breaking post-Bachelor rules. "We've been together for the past three months," Girardi says.

"Sneaking around?" DeGeneres asks.

"Yes," Pavelka admits. "Illegally."

"But we're engaged so we're allowed to sneak around," Girardi says.
