Cristian Castro has no shame and has bared his bum again for the whole world to see, but this time without the infamous "saiote." Earlier this month the 39-year-old singer tweeted a photo that went viral shortly after posting it to the social network. The "No Podrás" hit maker was seen in a barely there G-string, unkept hair and smiling ear to ear like if he knew he was going to get a "happy ending" with the services to be rendered. The Mexican singer is known for his eccentricities, but this one took the cake at the turn of the new year.

The original tweet was captioned as, "masajito con saiote," which left everyone wonder what that funny word was. Many speculated that it was something naughtier, or the name of the masseuse. Castro left us scratching our heads for the better part of January trying to figure out what he meant and he finally revealed it during an Argentinean breakfast show. “Before anything, I would like to state that I want to marry this girl because she gives incredible massages,” he said. “I found it very funny that I had to wear a ‘saiote.’ They’re disposable, you see?”

Cristian has been on a promotional blitz for a series of concerts he is performing in Mexico and the main topic has 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 on our gallery above and see more pics here.
