The real-life “Jackie Brown” flight attendant who allegedly ditched two suitcases full of cocaine at a Los Angeles airport tearfully defended herself to her broken-up father.

“Somebody gave her the bag,” her sullen dad told The Post on Saturday outside the family home in South Jamaica, Queens.

The father, who wouldn’t give his name, recalled the emotional encounter with his little girl, 31-year-old Marsha Gay Reynolds, just before she landed behind bars on Wednesday.

“She broke down, of course,” he said slowly, in a hushed voice. “She said she didn’t know what was in” the luggage. “I’m not in a good place right now,” he confessed, looking at the ground.

Prosecutors aren’t buying her story and believe Reynolds had carried drugs before and only got cold feet after being randomly stopped at an LAX checkpoint for airline workers.

The incident came as “nothing less than a shock” to a longtime pal who told The Post he used to help Reynolds with English homework while she was a student and track athlete at NYU, from which she graduated in 2007.

“She was just such an ordinary kid,” said the friend, who spoke on the condition of anonymity.

“I only remember her as the nice, thoughtful, beautiful girl who was going to college, working and keeping in shape,” he said.

The two met on a photo shoot in 2006, and he photographed and attended several of her birthday parties. In photos from her 25th birthday bash at a Queens venue in 2009, the glamour girl gracefully posed with friends in a pink and black gown.

The JetBlue worker was heading to board a flight to La Guardia Airport on Friday when she kicked off her Gucci heels, dropped her bags stuffed with 60 pounds of drugs — $3 million worth — and bolted, according to police.

“She knew if she dropped both [her bags and heels], she’d be able to run away more quickly,” said Marshall McClain of the Los Angeles Airport Peace Officers Association. “She was then able to hotfoot it out of the terminal, down an up escalator while barefoot, where we assume she got into a car and took off to parts unknown.”

McClain told the Los Angeles Times he doesn’t think it was Reynolds’ first rodeo.

“I don’t believe anybody would trust a mule with that amount of dope the first time out,” he said.

Following the drug dump, Reynolds, who is a nursing student at Mercy College, caught a flight to New York and holed up in the Hilton hotel near JFK Airport, sources said. She surrendered to authorities Wednesday and was charged with possession with intent to distribute cocaine.

Brooklyn Judge Viktor Pohorelsky had granted Reynolds a $500,000 bail package Thursday but stayed the ruling until California authorities could weigh in. The following day, California federal Judge Andre Birotte Jr. ordered that she remain detained until she faces an arraignment for drug raps there on April 7.
