Paris Hilton has revealed she is single after splitting from a recent "summertime fling".

The hotel heiress was photographed kissing Ralph Lauren stud Josh Upshaw following her break-up from model River Viiperi this summer (14), however, Hilton has opened up about her latest love disaster and explained she is no longer dating anyone.

She tells U.S. Tv host Wendy Williams, "I'm single. That was just a summertime fling.

She continues, "I'm not looking for anything right now, I'm just focusing on myself... But, when I do look for a guy, I just think it's most important to find someone who's really loyal, who I can trust, who can be my best friend, who makes me laugh."

Hilton has a long list of broken-hearted ex suitors, including shipping heir Stavros Niarchos, Doug Reinhardt, Cy Waits, Jason Shaw and rocker Benji Madden.
