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 Thursday, 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 460,000-square-foot 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 told CNN’s Larry King
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.”
