Cristian Castro has been enjoying the newfound fame after a photo he uploaded went viral. The 39-year-old Mexican singer shared a photo with his followers on Twitter that revealed his bum, with a goofy smile and a small string around him called "saiote." At first, we speculated he was going to receive a "happy ending" with his massage, but it turns out that "saiote" is the name of the disposable underwear. Now that the whole world knows what his bare bottom looks like, he wants to take it one step further and pose for an adult magazine.

"I am looking to pose nude in Playgirl, I hope that I can do it soon," he told El Nuevo Día. "I feel that I can retire soon. People love my butt, maybe I'm in the wrong career path." The image went viral in minutes, but that was not the intention the "No Podrás" singer had in mind. "I was not going to tweet it, but I saw it at night and I said, 'this is funny, because I look fat, I look kind of crazy and I am raising my little butt,' and I thought it was cute, I didn't find it pornographic nor offensive."

Castro has no problem showing off and he actually posed for photographers without the infamous "saiote" when he lost a bet with Facundo. Cristian had been on a promotional blitz for a series of concerts he was performing in Mexico in late January and the main topic had been the scandalous photo. The irreverent radio host, Facundo, challenged the singer to bare it all once again, but this time without his paper thong. Castro agreed to do it and dropped his pants to reveal his bum for the world to see leaving us ill for a second time this month. Check out the NSFW photo here and see more pics here.
