Paris Hilton is building on her famous name.
Childrens Hospital Los Angeles announced Thursday that the hotel heiress has made an "extremely generous" donation toward the construction of a new 460,000 square-foot medical tower at the downtown facility.
Hospital officials didn't specify the amount Hilton gave, but said her contribution will trick out a double-patient room in the Childrens Center for Cancer and Blood Diseases, which is slated to open in 2010.
"I am so happy and fortunate to announce my support for Childrens Hospital Los Angeles," Hilton said in a statement. "The children I have met through my [involvement] at Childrens Hospital have truly touched my heart."
