Taylor Swift has blasted an online rumor which claimed that the award-winning 18-year-old singer is pregnant by ex-boyfriend Joe Jonas.

“I read a very creative rumor this morning saying I’m pregnant, which is the most IMPOSSIBLE thing on the planet. Take my word for it. Impossible,” Taylor blogged on her Myspace page Thursday, implying that she is still a virgin.

“I have devoted my entire life to not having something like that happen,” an upset Taylor continues. “It’s really, really scary that someone can just say something and it gets spread around the Internet and all of a sudden it’s a verified rumor, with no grounds.”

“I didn’t do anything to provoke that. Like I’m sitting there thinking, like what? Did I wear the wrong shirt?”
