She is a headlining singer at the Tipton Hotel as well as the mother of Zack and Cody. She is a divorced mother, wise, and kind. She seems to love the twins a lot. She is sometimes overprotective of her sons, which they hate, but she does it for good reason. Arwin Hawkhauser has a crush on her. She has a younger sister who is never seen, and often dreams about George Clooney. Zack usually takes advantage of her (asking her for money, treating her like a maid, etc.), but at some points, tries to be more appreciative for what she does, like Cody. Carey found her talent for singing by mistake when she was at a talent show doing stand-up comedy.
Although Zack and her don't always get along, it is sometimes shown Zack really does appreciate her and love her. She tries to keep the boys away from trouble, but never succeeds. Later in the second season, she changed her hair color from blond to reddish-brown multiple times. As of Season Three, she has kept her brown hair and has grown it out a little. When she is trying to teach the boys a lesson (or in some cases, other characters) she uses a story from her past, which is always boyfriend related, leading to Zack and Cody or the other characters groaning. She was also once seen wearing rubber duck pajamas. It is said that she doesn't cook or cooks badly.
In the episode "Sleepover Suite," Carey states she is a Virgo. She likes the color blue and prefers wearing short dresses. She also dyed her hair blue in the other dimension of the episode when Zack and Cody went to a parallel dimension. Whenever around London Tipton, she would always be falsely yet humorously helping her since London always exclaims that Carey told her everything. She did not board the S.S Tipton so that she could keep her job but Mr Moseby is watching Zack and Cody for her. However, Carey has visited the ship along with Kurt. When the ship docks in Japan, Zack and Cody visit their mom who is doing a new commercial.
In 2007, Kim Rhodes became pregnant; however, the show didn't incorporate it in the series. Carey was seen putting her hand on her stomach and she did have a bump at the show's end.
