Socialite Paris Hilton has revealed she is single after splitting from a recent “summertime fling”. The 33-year-old hotel heiress was photographed kissing Ralph Lauren stud Josh Upshaw following her break-up from model River Viiperi this summer. However, Hilton has opened up about her latest love disaster and explained she is no longer dating anyone, reported Contactmusic.“I’m single. That was just a summertime fling. 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 said. Hilton has a long list of former boyfriends, including shipping heir Stavros Niarchos, Doug Reinhardt, Cy Waits, Jason Shaw and rocker Benji Madden.
