How Do Kim Kardashian, Nicki Minaj Rank Among Instagram's Sexiest Selfies?

MTV News takes a look at the steamiest pics on social media, including perpetual posters Justin Bieber and Rihanna.

No filter necessary for these sexy pics, but some of your favorite celebrities' selfies might need to come with a NSFW warning. Everyone from [article id="1715737"]Kim Kardashian[/article] to Nicki Minaj is giving their followers an eyeful on social media. And, it's not just the ladies: Some of the hottest dudes in the game are also tantalizing fans with [article id="1711553"]sexy shirtless selfies[/article].

With more and more A-listers showing more and more skin on the Net, here's MTV News' round up of some of the hottest pics on Instagram.

Nicki Minaj

The rapper hardly held back on Instagram this week, posting a couple snaps of herself rocking nothing but leopard-print pasties. It lead the performer/fashion mogul to wonder if she should include the look in the Spring Collection for her Kmart fashion line. Fans will have to wait to see if they make the final cut — but chances seem slim.

Kim Kardashian

It was the photo that had Kanye West pledging "HEADING HOME NOW." This week, Kim made headlines when she put her post-baby body on full display in nothing but a skimpy white bathing suit. While there was very little cloth, noticeably not absent was Kim's famous bottom.

Nick Jonas

We know just how Nick might be spending his time now that the [article id="1715740"]Jonas Brothers are on hiatus[/article]. He'll likely be working on those now-famous abs, which he first flaunted and made quite a few headlines with over the summer.

Justin Bieber

Bieber might be the undisputed king of [article id="1711041"]leaving his shirt[/article] elsewhere when a camera is around. On any given day, the singer posts a shot of himself sans shirt. Not that the Beliebers are complaining.

Rihanna

Badgalriri can be found in all sorts of states of undress online. Whether [article id="1711857"]she's partying in Barbados[/article] or posing in very little clothing on her [article id="1714852"]"Pour It Up" video[/article] set, Rihanna does scandalous selfies like no other.

Ke$ha

Ke$ha's life really is [article id="1715608"]crazy and beautiful[/article]. The singer/reality star (whose show, "My Crazy Beautiful Life," premieres October 30 at 10:30 p.m. ET/PT on MTV) lets fans into her world on social media, giving them eye-popping looks at her life.
