Paris Tight Lipped About Nicole

Though Paris Hilton was swarmed by questioning photogs, the heiress kept quiet about Nicole Richie's checking into a treatment facility.

As she made her exit from Hollywood hotspot Area, a cameraman repeatedly asked Hilton, "is it true Nicole is in rehab?" Paris evaded the line of questioning the only way she knows how - by pretending to talk on her cell phone.

Nicole checked herself into a private facility for an undisclosed treatment yesterday where, according to her publicist, she is "working with a team of doctors and specialists whose focus is nutrition."

And while the paparazzi crush followed Paris all the way to her vehicle, she can rest easy knowing she garnered the most attention from the photogs all night - beating out the likes of Lindsay Lohan and Kristin Cavallari.
