The Keeping Up With the Kardashians' star posted this photo on Instagram yesterday during her PacSun holiday shoot, simply saying: "Exhausted" and she exactly like her older sister Kim Kardashian.
She definitely looks older than her 17 years and her lips are much larger and fuller than we've ever seen before. They're almost double the size we're used to!
We wonder if she got lip injections or if she just used a serious lip-plumping gloss on set for her photo shoot?
Kendall's been making headlines lately since she and her younger sister Kylie went to a club that's supposed to be 21 and older.
"Shut up with these stupid rumors and stories," she Tweeted yesterday in response to reports she and her sister used fake IDs to enter the club.
Do you think Kendall got work done?
