Photographed by Terry Richardson for the cover of the November issue, a scantily clad Lea Michele and Dianna Agron create a Cory Monteith sandwich, posing seductively on either side of their co-star.
Agron wears an off-the-shoulder black crop top with a blue miniskirt accessorized with the groping hands of Monteith and Michele, while a leggy Michele sizzles in hot pink lips, shoes, panties and bra with a pale pink crop top and over-the-knee socks.
And oh yes, Monteith, who sports a striped team jersey and gray pants, also has his hand on Michele's bottom.
In the accompanying interview, Agron, who plays popular cheerleader Quinn Fabray, admits that the steamy photo session might not stop Internet chatter that she and former roommate Michele are more than just friends.
"When it was just Lea and me, I was like, 'We're in skimpy clothes, we're up against each other. This is feeding those rumors,'" says Agron, who poses inside the magazine in a hiked-up plaid skirt, sheer white crop top over a red bra, and red stilettos with white socks. "I've never been shot in so little clothing."
Nor has Michele. The actress, who plays diva overachiever Rachel Berry, appears in two photos wearing a blue and white baseball tee that is ripped open to reveal a blue bra; white panties; white tube socks with blue stripes; and hot pink pumps.
In one shot, she lustily licks a lollipop in a locker room; in another she plays with her hair while seated on a bench, legs akimbo.
"I don't know how they got me to do half the stuff I did," she tells GQ. "But I was in really good shape this summer, so..."
Michele admits that she wasn't always so confident about her appearance but that all changed when she saw the Barbra Streisand's movie "Funny Girl" as a kid.
"Barbra's character is a funny-looking girl with a ridiculous voice who becomes a famous Ziegfeld girl," she explains. "But she can never do anything serious. She's like, 'I can't sing about how beautiful I am, because I'm not beautiful. So I'll make it funny.' I was like, That's me. I look like her. I understand her."
So, naturally, when Michele was told to get a nose job to boost her acting career, she refused.
"I was one of the only girls in my high school that didn't get one," says the Bronx-born, New Jersey-raised star. "And if anybody needed it, I probably did. But my mom always told me, growing up, 'Barbra Streisand didn't get a nose job. You're not getting a nose job.' And I didn't. F-- those people.
"That's why I'm proud to be on a positive show and to be a voice for girls and say, 'You don't need to look like everybody else. Love who you are.'"
While being surrounded by two gorgeous women may certainly seem tempting for Monteith, he swears he's never engaged in any off-camera hanky-panky. "There's a beautiful chemistry to this show," he says, "and messing with that would be dangerous."
