Lauren Conrad has denied reports that she is dating Derek Hough.
The former Hills star was first reported to be romantically involved with the Dancing with the Stars professional in early October when the two were spotted out at Jason Scoppa's weekly live music show at the Sayers Club in Hollywood.
However, Conrad has since insisted that she is not dating anyone.
"[I'm] single, having fun," she told E! Online.
A source previously told the website that the two had been on "a few dates together."
Conrad split from her long-term boyfriend Kyle Howard in June.
In July, the reality star was also rumoured to be dating Teen Wolf star Colton Haynes after she was seen flirting with Haynes at the HTC Status phone launch.
Kristin Cavallari - who appeared opposite Conrad on The Hills - became the third contestant to leave the current series of Dancing with the Stars last week.
