Is it hot in here or is it just us?

Supermodels Kate Upton, Miranda Kerr and Amber Valletta (who fans will also recognize from her acting roles in Revenge and Hitch) star in some very NSFW pics for V magazine's new Fall issue -- all while posing in bed. Shot by photographer Sebastian Faena, the eyebrow-raising spread is a tongue-in-cheek nod to supermodel Linda Evangelista's famous 1990 Vogue quote that she and fellow model Christy Turlington "don't wake up for less than $10,000 a day."

PHOTOS: Stars in Their Underwear

Here's 23-year-old Kate rocking a lacy white corset.

And 32-year-old Miranda showing off her booty in a skimpy mesh bodysuit.

But the most daring is obviously 41-year-old Amber, who straight-up goes topless.

Kate actually opened up about her reasons for not posing nude earlier this month, though clearly, this picture is pushing the boundaries. "For me those [nude] photos are art," she told Details. "Your body is art, your body is beautiful, and to be photographed in that way is amazing and it’s received in a very positive way. But with social media and the Internet and not so great blogs and the attention like that, I don't think that my pictures would be received in the way that I'd want them to be received. That's why I've stayed away from them."

However, theSports Illustrated cover model has zero problem posing in bikinis. "I've always been comfortable [in a bikini]. It was everyday wear," Kate candidly told ET about growing up in Florida, when we caught up with the blonde beauty in February 2013.
