What gave Cody Simpson this lizard-like tongue?
"I had, like, five blue Warheads," Simpson told MTV News. "After, like, three, I saw my tongue obviously started getting blue, and I was like, 'I might as well have two more.' "
Although we don't know the entire story behind these next five Instagrams, they're the MTV News team's favorite from the week:
Zac Efron posted this pic from the Philippines. The "Lucky One" star four-wheeled up the side of Mayon Volcano, an active volcano in the province of Albay, on the island of Luzon.
"Pretty Little Liars" star Lucy Hale snapped this Instagram with castmates Julian Morris, Keegan Allen and Tyler Blackburn. She captioned the photo "4 of my favorite gents," which is a little confusing, since we only count three dudes in the picture ... unless?
This political pic of Usher and President Obama received a lot of attention for the R&B superstar. Not only did it grace Instagram's Popular feed, but it also obtained more than 13,000 likes and 737 comments and counting.
It's not all about diving for Tom Daley. The 18-year-old Olympian showed off his tobogganing skills in this Instagram picture earlier in the week. While the athlete proved he has what it takes to compete in the Summer Olympics, we're taking bets that he won't be joining Great Britain in bobsledding during the 2014 Winter Games.
Kylie Jenner took over big sister Khloé Kardashian's account for this Instagram photo. Even though Kardashian's account was "hacked," it didn't stop her fans from showing some love. Within four hours of posting the pic, it received more than 78,000 likes and 663 comments.
