PopUps: Nick Jonas's Marky Mark Deja Vu

Nick Jonas is officially no longer a little boy anymore. Thank the lord.

The 22-year-old pop star channeled Marky Mark Wahlberg for a photo shoot he did for Flaunt magazine that was published this week.

To solidify that he isn't a Jonas brother anymore, the singer got raunchy for the photo shoot, leaving behind his Disney days.

The pictures start off with the youngest Jonas brother wearing full ACTUAL CLOTHES but things take a sharp turn down Hotsville when he sheds his shirt and eventually his tight jeans, wearing nothing but his Calvin Klein underwear, at which point the spirit of Marky Mark whispers, "Do it Nick."

And he does: Nick Jonas grabs his crotch and makes a similar Marky Mark face from his iconic 1992 Calvin Klein campaign ad campaign.

Things somehow even get steamier in the next photo where Jonas shows off his butt cleavage.

It may not come to a surprise to some that Jonas is bearing it all - last month the singer hit up a New York City gay club to perform his single "Jealous" and gave an impromptu strip tease to a large crowd.
