Passage: Meester was born in Fort Worth, Texas, to Constance Lynn (née Haas) and Douglas Jay Meester. Her father is a real estate broker; her mother is a writer. She has two brothers; an older brother, Douglas Logan Meester (born 1983), and a younger brother, Alexander "Lex" Meester (born 1994). At the time of her birth, Meester's parents were serving time in a federal prison for their involvement in a drug ring that smuggled marijuana from Jamaica to the United States. Constance was able to give birth to Leighton in a hospital and nurse her for three months in a halfway house, before returning to prison to complete her sentence. Her paternal grandparents cared for Meester during this period. She has maintained that her parents gave her a normal upbringing and, despite their criminal past, has stated, "It made me realize that you can't judge anyone—especially your parents—for what they've done in their past, because people change." She grew up in Marco Island, Florida, where she participated in productions at a local playhouse. Her parents separated in 1992.When she was 11 years old, Meester and her siblings moved with their mother to New York City. She attended the Professional Children's School and began working as a model with Wilhelmina, booking a Ralph Lauren campaign shot by Bruce Weber, and working with then-photographer Sofia Coppola. Meester also booked commercials for Tamagotchi and Clearasil, and modeled for Limited Too alongside Amanda Seyfried. At age 14, she relocated to Los Angeles, California and attended Hollywood and Beverly Hills High Schools. Meester then transferred to a small private school and graduated a year earlier than normal.
