Nelly has apologized after a sexually explicit video was shared on his social media account. 

On Tuesday, the 47-year-old singer's Instagram Story had a video of him receiving oral sex from a woman.

It wasn't long before the R&B crooner noticed the video and took the post down. The "Hot In Herre" singer issued a statement via his rep to Fox News Digital after removing the clip from his social media.

"I sincerely apologize to the young lady and her family. This is unwanted publicity for her/them," he said. "This was an old video that was private and never meant to go public."

The singer's team told Fox News Digital that they are concerned that Nelly was hacked as they're investigating a breach that they fear could also see his financial information, personal documents and passwords end up online somewhere.
