Beautiful (2000)

Mona Hibbard steadily advances as an American beauty queen in spite of her less than congenial temperament. Her best friend from childhood, Ruby, has the patience of a saint, which is why she's the one person who is willing to help Mona pursue her ambition. Ruby even helps her to hide the secret that would completely derail Mona's plan to capture the "Miss American Miss" title: an illegitimate daughter, Vanessa. Her biggest obstacle is losing her killer instinct for her maternal instinct.
