When Sean Lowe and Catherine Giudici made their relationship official during The Bachelor, we feared Sean's raging lack of premarital sexy hormones would rub off on her. And rub off they did. Sean and Catherine are abstaining from hanky panky until the night of their wedding, which means they're both born-again virgins.

But guys? It looks like Catherine has cashed in her v-card. No wait, sorry –– she's cashed in her Sin City v-card, by which we mean she just took her inaugural trip to Las Vegas. Sigh, almost as exciting as her and Sean doing the horizontal bump, right?

"Vegas Virgins no more," Catherine posted to Instagram on August 2, along with a photo of herself and her friend, Laura Caperton, posing by some faux Greek statues.

Hmmm, looks like Catherine's on a trip with her gal pals and Sean Lowe (who's doing a few publicity appearances), and judging from pictures like this, they're having a fabulous time. Yep, that's Sean voguing with a couple Gladiators at Caesars Palace. Don't even worry about it.

To paraphrase the immortal words of Madonna, Sean and Catherine are both like a virgin...touched by a Roman beefcake for the very first time.
