Oh Paris! Will she ever quit trying? Quick note: When you have to be topless, wearing false lashes and have your mouth slightly open, you're trying way too hard to be sexy.

Rihanna is the queen of trying too hard. This photo of her doesn't exactly scream "I'm just a regular girl."

What's truly disturbing about this photo is Jessica Simpson is clearly quite pregnant yet still feels the need to suck in her cheeks and pucker her lips ever so slightly so she looks thinner in the face.

Vanessa Hudgens is also a fan of the pouty lip look when taking her selfies.

Most celebrities use their Instagram accounts to show the world how to down-to-earth they are, but not Lea Michele. She chooses to remind her fans that she walks the red carpet nightly and that she looks good doing it.

Anyone who's ever met Miranda Kerr can attest to the fact that she's hyper-aware of her image (don't even think about snapping a photo of her without her first getting a touch-up from her makeup team), so it's a little hard to believe that this was a perfectly candid shot.

Madonna is new to Instagram, so she didn't realize that showing a pic of her sweaty cleavage would make people gag, not swoon.

If you're ever interested in learning about the evolution of "duck face," just take a gander at Kim Kardashian's Instagram account.

Heidi Klum may be in her 40s, but she wants everyone to know how sexy she still is. Don't worry about forgetting. She'll remind you every day through her half-naked Instagram selfies.

Even Justin Bieber is guilty of trying too hard. Try to find a selfie of him that doesn't include this "who, me?" expression.
