Supermodel Tyra Banks is happy to attend Sunday's I Have a Dream Foundation charity luncheon at L.A.'s House of Blues. The nonprofit provides children from low-income communities with educational and mentoring opportunities. Banks, who recently opened up to PEOPLE about her own personal struggles, is a philanthropist in her own right: Her T-Zone summer camp is aimed at boosting teenage girls' self-esteem.
