Selena Gomez Shakes Things Up With Her Skintight Pants

Talk about giving Khloe Kardashian a run for her money in the camel toe competition!

On Monday afternoon a cheerful Selena Gomez went to a friend's house in Hollywood, and the 21-year-old singer showed off her slim figure in a super tight pair of stretch pants. Her bod looks amazing, but that can't be comfy!

While Selena may be all smiles here, we have to wonder what's going on with the starlet and on-again boyfriend Justin Bieber, as she JUST posted a smokin' hot selfie on Instagram and wrote, "Class never runs scared. It is sure-footed and confident, and it can handle whatever comes along. Class has a sense of humor. It knows that a good laugh is the best lubricant for oiling the machinery of human relations."

Is that some sort of a cryptic message to him?! Seeing as his former flame Chantel Jeffries posted the pic below late last night, we have to wonder if Jelena are on the rocks just weeks after their latest reunion!
