Romeo Santos is known for surprising his fans with kisses on stage, but he was the one that got a surprise at his Dominican Republic concert.

The Bronx-born artist returned to Santiago, Dominican Republic after not having performed there in 15 years, according to TV Notas. After bringing a fan up on stage and giving her a kiss, she reached for his privates. A picture features Santos with his mouth wide open, and his hand over her hand.

This is not Romeo Santos' only concert moment to go viral recently.

A video of Santos kissing a woman onstage has also been much discussed. He and the woman ended up hiding beneath sheets, where they simulated sex. The woman has since spoke to a Colombian radio show, according to Las Mañanitas Show, and explained that the two were just acting. They reportedly didn't kiss or do anything else, and she said the activity didn't warrant being called names. This video, which was shared by MelmaMusicTV, has more than 1.7 million views.

In a recent interview with Vulture, Romeo Santos said that calling himself Romeo, a name he took from the Shakespeare work "Romeo and Juliet," was a way for him to come out of his shell.

"I was extremely shy when I first started in the business," he said. "I didn't know how to act onstage, I would sing and keep my head down to avoid eye contact with the audience -- that wasn't going to be appealing to women."

So he drew inspiration from other artists and tried to find something special to offer his audiences.

"I wanted to show people I'm like a modern Romeo," he said. "I'm romantic, but I can also be seductive. I can be cool and charismatic, swagger-type. Onstage, I'm Romeo. That gave me confidence, self-esteem."
