After 14 long years, Nelly has responded to one of the biggest questions in hip-hop pop culture history: why did Kelly Rowland message him using an Excel spreadsheet in their old school music video for "Dilemma"?

The song was a smash hit in the early 2000s about the forbidden love between a guy and a family woman, played by the Nelly and Rowland. It became the most successful song in the rapper's entire music career and was responsible for finally making Rowland more than just a backup vocalist for Beyoncé Knowles in their group, Destiny's Child.

In the video, which was filmed on the set of "Desperate Housewives" in the backlot of Universal Studios, the pair is seen hanging out on their porches before finally dancing together out on the street. Years after it was released in 2002, it went viral again after the Internet took notice of a small mistake in the video that had a lot to do with technology.

For a few seconds, we could see that Kelly texts Nelly, "WHERE YOU AT? HOLLA WHEN YOU GET THIS" with her Nokia EPOC Excel spreadsheet application.

A few days ago, Nelly finally addressed the mystery behind the Excel spreadsheet text in an interview on The Project.

"That was the thing at the time. That was the new technology at the time. It looks a little dated now, I can see that," he said.

While Excel does look quite outdated now, Nelly was wrong about it being "the thing at the time" because it was never able to send text messages.
