Even though Shelly and J.T.'s relationship is the predominant storyline, the series does explore the relationships of its supporting cast; Donovan and Rita date each other, and the quite-selective Nick attempts to find the perfect partner. Donovan owns the Z Lounge, which is described as "one of Miami's hottest clubs" and serves as one of the places where the group often meets. Other frequently recurring characters include Shelly's younger love interest Grant (Sharif Atkins), Janie's husband Marty (Reggie Gaskins), and Shelly's mother Beverly (Penny Johnson Jerald). Several celebrities also make cameo appearances on the show, including Queen Latifah, Missy Elliott, Brooke Burke, Vivica A. Fox, and Cedric the Entertainer.
