While we fully enjoyed Monday's Gossip Girl, "The Lady Vanished" (follow the links for our review and Round Table), the most compelling 30 seconds may have next week's promo.

"The Sixteen Year Old Virgin" refers, of course, to little Jenny Humphrey, who's getting pressure from bad boy Damien to take their relationship to the next level despite her age.

Will this be the night J cashes in her v-card?

Meanwhile, Lily tells Rufus the big secret she has been keeping from him, even though she knows it's a huge risk, and Dan and Vanessa explore a new stage of their friendship.

Also, from the looks of the promo, Jack Bass makes a surprise (and unwelcome) return, Chuck is forced to make an difficult decision about his hotel (while being accused of harassment), Serena gets confronted about her past, and Nate punches someone ... or gets punched. Hard to tell!

We've added a photo gallery from the episode that we'll do an article on tomorrow. For now, check out the promo for "The Sixteen Year Old Virgin" and tell us what you think ...
