Sean "Diddy" Combs is expected Saturday night at the Ritz-Carlton to host the black-tie Joy to the World gala to benefit local families in need, organizers say.

Music producer Jermaine Dupri, actors Vivica A. Fox, Boris Kodjoe and Lance Gross, and some cast members from Bravo's "Real Housewives of Atlanta" will also attend, according to Nia Ngina Meeks, who is working on the Joy to the World festival weekend of events.

State Sen. Anthony Hardy Williams and Mayor Nutter will speak at the gala along with Joy to the World festival founder Tyrone L. Gilliams. The gala is part of a weekend of toy drives, bowling, concerts and kids' entertainment all designed to help local children and families in need.

Some highlights include Thursday's bowling event with Eagles receiver DeSean Jackson, comedian Kevin Hart, hip-hop star Fabolous and model Melyssa Ford at North Bowl (909 N. 2nd) and a record-release party Friday night with Jamie Foxx at The Vault (470 N. 2nd).
