In a world of celebrities behaving badly, these 20 stars balanced things out.
Lady Gaga, a leader in gay-rights issues, takes the No. 1 spot on a new list of the “Top 20 Celebs Gone Good” in 2010, honoring stars for their charity work. Alicia Keys, who is devoted to fighting HIV and AIDS, was the runner-up.
The list is compiled by DoSomething.org, a charity leader for teens and social change. – Tim Nudd
