R&B fans were thankful for super-producer Polow Da Don, who brought Chris Brown, Keri Hilson, and Lloyd together for Zone 4’s 4th Annual Thanksgiving Carnival in Atlanta earlier this week. Co-hosted by Ludacris and Big Boi, the charity event attracted over 5,000 people who enjoyed free rides, food, giveaways, and music. In addition, 1,000 turkeys were given away to families in need. Check out some of the highlights in the clip above.
