Some intentional, some not!
Celebrities left little to the imagination in 2015, proudly baring their bootys in risqué photoshoots and flaunting their figures in sexy Instagram posts. While not all of these NSFW pics were intentional ("Sorry," Justin Bieber), here's a look at some of the most memorable naked moments we couldn't help ourselves from staring at this year.
John Legend
When you’re married, anything goes -- that is, if your spouse is Chrissy Teigen! The mom-to-be took to Instagram in July, sharing a sneaky snap of her husband's bare backside.
Kim Kardashian
The TV personality bared it all while trying to 'break the Internet' with her Paper magazine photoshoot in 2014, but that didn't stop her from doing it again in 2015. While she shared a handful of naked photos this year, her pregnancy selfie was by far the most talked about of them all.
Naya Rivera
Kardashian wasn't the only one to pose naked while carrying a baby. The same day the KUWTK star posted her pregnant selfie, Rivera, who has been accused of copying Kardashian on multiple occasions, shared behind-the-scenes photos from her revealing photo shoot with Yahoo!
Selena Gomez
The "Good For You" singer proved that you can still be classy with your clothes off. Gomez stunned while wearing nothing but a pair of black panties in the black-and-white photoshoot for her newest album, Revival.
Khloe Kardashian
The reality TV star stayed true to the title of her book, "Strong Looks Better Naked," in October. Two months later, she showed off her bum again -- this time with a side of glitter -- in what she dubbed a literal "bomb ass photoshoot" exclusive to her app, shot while she was vacationing with her famous family in St. Barts.
Pamela Anderson
No surprise here! After Playboy announced they'll no longer be featuring pictures of naked women earlier this month, ET learned that the 48-year-old model would be gracing the cover of the magazine's last nude issue. Just a few weeks earlier, Anderson shared a photo of her baring it all on a boat.
Emilia Clarke
The Game of Thrones star was named Esquire's Sexiest Woman Alive this year, and after seeing the gorgeous photos from the mag's shoot with the British actress, we have to admit, we agree.
Justin Bieber
The "Love Yourself" singer made headlines in October when nude photos clearly showing off his package from his vacation in Bora Bora were published without his permission. Looks like Bieber doesn't mind showing off his backside, however. He posted, but later deleted, a pic of his bare bum to Instagram.
Lebron James
Like Bieber, the NBA pro was also the victim of a public mishap this year. During Game 4 of the NBA finals in June, cameras caught James accidentally exposing himself while fixing his uniform prior to the start of the game.
Amy Schumer
Wearing only lacy underwear and high heels, the Trainwreck actress looked as confident as ever while putting her figure on display in a shoot with famed photographer Annie Leibovitz for the 2016 Pirelli Calendar. "I felt more beautiful than I've ever felt in my life," Schumer explained. "I felt like it looked like me."
Demi Lovato
The "Confident" singer praised Schumer for her nearly nude shoot, reposting the photo to her own account with the caption, "This is the perfect example of a #CONFIDENT woman taking a giant s**t on society's twisted views of what perfection is." Lovato went fully naked herself (and makeup-free!) in a spontaneous photoshoot released by Vanity Fair in October.
Sharon Stone
Proving that age is nothing but a number, the 57-year-old actress stunned in her flawless nude photoshoot for the September issue of Harper's Bazaar.
Amber Rose
The model stripped down for GQ, and despite the men's magazine calling her "hot" with a "unique, otherworldly perfection," Rose wasn't too happy about the content in the accompanying interview, which referred to her as "Kanye's infamous ex" and "Wiz Khalifa's baby mama." We think it's safe to say all eyes were on her assets, though.
Miley Cyrus
While we've seen plenty of provocative pics this year, the most racy of them all is without a doubt the 22-year-old singer's outrageous shoot with Candy magazine, in which she appears topless while sucking on a police baton and playing with sex toys. She's just being Miley?
