From NY Post:

September 26, 2006 -- PARIS Hilton's haunches or Jessica Biel's butt? City women are flocking to plastic surgeons in search of a booty befitting their favorite starlet. At one new Upper East Side clinic, posterior patients can request a specific celebrity's backside. Popular requests include Eva Longoria, Lindsay Lohan, Jessica Simpson, Paris Hilton and Jessica Biel. Noticeably absent from the list is a certain Bronx-born booty bombshell, Jennifer Lopez. The new rear to bear is smaller, tighter and "more refined," according to Dr. Brad Jacobs, who's unveiling his "Star Butts" clinic today in his office. Surgeons re-create famous fannies by transferring patients' unwanted belly flab or saddlebags to their bottoms.
