Hotel heiress Paris Hilton has been forced to explain her steamy kiss with another female, after a photograph of their clinch was published on the Internet.

According to the Internet Media Database, the blonde beauty was seen topless and kissing stunning MTV Latin American VJ Eglantina Zingg in the picture - but the 24-year-old claims it was just a bit of fun.

"We were joking around at a photo shoot for a magazine. It wasn't sexual. But it's scary that someone out there can get into your private device," Hilton was quoted as saying.

Hilton was referring to the hacking of her mobile phone that led to its contents, including the same-sex kiss photograph, to get on to the Internet.
