LaCieniga Boulevardez is a Mexican-American rival of Penny Proud. She's from the show The Proud Family.
LaCienega is stuck up and conceited, but deep down inside, she's insecure and a little jealous of Penny because she's more down to earth. She and Penny constantly antagonize each other and Penny is usually stuck with her. In the show, LaCienega is able to convince her parents and the Prouds that she is a very sweet and moral young lady, while in the fact, she is arrogant, vain, snobbish, and obnoxious. However, deep down she likes Penny a bit, but would never publicly show it. She is also in an R&B girl band called LPDZ. Eventually, all the adults are able to see past her false façade and soon She no longer even attempts to act civil around them, rather acting like her real self. When she's actually a friend to Penny, they get along real well, like in the episodes One in a Million, The Camp, The Counselor, The Mole, and the Rock.
LaCienega is a Latin-American girl who has long brown hair with a red flower barrette, wears a pink shirt, red jacket, blue jeans, and blue shoes with pink socks.
