NASCAR drivers Danica Patrick and Ricky Stenhouse Jr. split after five years together:  A spokeswoman for Patrick confirmed on Monday (12/18) that the drivers are "no longer in a relationship."

Patrick didn't attend the season-ending awards ceremony last month in Las Vegas with Stenhouse, who was honored for making NASCAR's playoffs in 2017.

That led to speculation about the most famous couple in motorsports.

It was an unconventional pairing. They raced against each other weekly, and over the course of their relationship they clashed competitively, leading to post-race disagreements.
