LOS ANGELES: Paris Hilton is making good on her promise to become a better person.

The 27-year-old socialite made an “extremely generous” donation toward the construction of a medical building at Childrens Hospital Los Angeles, hospital officials said on June 26, although they did not specify the amount.

“The children I have met through my involvement with Childrens Hospital have truly touched my heart,” Hilton said in a statement. “I am proud to make a donation and lend my name to the fundraising effort to help children who are facing terribly serious illnesses.”

The 43,000-square-metre Childrens Center for Cancer and Blood Diseases is expected to open in 2010.

After spending about 23 days in jail last year for violating probation on alcohol-related reckless driving charges, Hilton said on CNN that the experience caused her to re-evaluate the role partying played in her life. She said she wanted “to help raise money for kids and for breast cancer and multiple sclerosis.”
