"Star Wars" icon Carrie Fisher allegedly had a drug relapse about a month before she suffered a massive heart attack on a flight from London to Los Angeles Dec. 23.
"Carrie had relapsed around Thanksgiving," said a source, RadarOnline reports. "I saw her myself high as a kite once, not that long ago."
"Some of her friends I talked to doubted she was ever totally clean and sober because she got doctor's prescriptions to treat her bipolar disorder, depression and anxiety."
The source said: "Ironically, she said to me, 'You're too old to get high anymore, dear.'

Fisher, who had publicly spoken of her addictions to LSD, alcohol, cocaine, heroin, and pills, passed away on Dec. 27 in a Los Angeles hospital after experiencing a medical emergency on her flight from London four days prior, the Daily Mail reports.
She spoke frequently about her addictions in interviews. She had even revealed she used cocaine on the sets of "The Empire Strikes Back" and "Return of the Jedi."
She had gone to London to appear on the TV series "Catastrophe" and "The Graham Norton Show," where she promoted the recently released "Rogue One: A Star Wars Story." In the movie, a young version of her Princess Leia character appears at the end saying one word: "Hope."

She told Norton she wanted "a female planet" in "Star Wars" and presented her latest book, "The Princess Diarist," on his show that aired Dec. 9.
She shared with Norton's audience that she had forgotten about writing the diaries years ago when she was 19, while she had been having an affair with her "Star Wars" co-star Harrison Ford. She unearthed the journals in a storage room.
Norton commented that the news of her affair with Ford triggered a media "sensation," adding that he found it extraordinary they never spoke of the affair to each other again.
"I became friends with his second wife then, so we saw each other a lot... I can literally remember three times… I of course made some oblique reference to it, and he went 'urghhh'," Fisher responded.
Norton stated Ford would probably have to talk about it for the rest of his life.
Fisher's mother, famous Hollywood actress Debbie Reynolds, posted a statement on Facebook about her daughter's death on Dec. 27.
"Thank you to everyone who has embraced the gifts and talents of my beloved and amazing daughter," Reynolds wrote.
"I am grateful for your thoughts and prayers that are now guiding her to her next stop. Love Carrie's Mother."
