She has blonde hair and wears a schoolgirl like attire. During GTA V, the player can get dances from Cheetah, however, once her like meter is filled, she won't be available to take home. This is due to the fact that Cheetah does not sleep around.
There is an unused, yet working phone number in the game's files that corresponds to her, suggesting that you were to be able to take her home during story mode. The same applies to the other girls who cannot normally be taken home. The number is fully functional, but as no dialogue was recorded for the scenes, they will be silent.
