"The only person pregnant in Lauren Conrad's life is her publicist and you can quote me on that," Conrad's representative toldOK! Weekly in a Friday report.
The 22-year-old was the presumed subject of a "blind" blog posting early last week, according to OK!, which started the pregnancy rumors and prompted her representative's denial.
"This Hills and/or Laguna Beach star is pregnant. Now if we could just figure out the daddy," read the posting, OK! reported, adding "readers then deducted" it was about Conrad.
While a baby isn't her immediate future, Conrad still has a lot to keep her busy.
She made her designer debut at last week's Mercedes-Benz L.A. Fashion Week event and is also gearing up for the continuation of The Hills' third season, which will premiere Monday, March 24 at 10PM ET/PT on MTV.
