This is really Aaron Carter.
The brother of Backstreet Boy Nick and former Dancing With the Stars contender has apparently been hanging out with The Situation. Look at this physique ...
Aaron Carter shirtless. It's a tad intense. We are scared.
What this picture, which Carter Tweeted, has to do with the messages he posted along with it, we have no idea, but here's what the singer wrote last week:
"I've been at Johnny Wright's compound working on my mind, music, and body for a new album release," he wrote, followed by "ahhhh yawn... here i go again!!!! 1000 pull ups today 7 mile run the 1000 sit ups, i can't stop myself."
Can you stop yourself? Tell us ... would you hit it?
