Playboy Playmate Ashley Mattingly posted a video from a hospital bed just two days before she took her own life.
In her final Instagram post, the 33-year-old said she had drunk too much alcohol and had been vomiting blood as she warned others to "slow down on the drinking".
She was found dead at her home in Austin, Texas on Friday April 17, two days after she is believed to have died.
Her final video had an animal filter over the top that distorted her voice and she was seen in her hospital bed with what appeared to be an oxygen tube.
Ashley said in the clip: "I'm sick with alcohol... don't drink it. Don't drink it. Leave it alone."
She captioned the video: "I'm not quarantined I took bad advice and drank too much which I vomoted a lot of blood.
"Please slow down on the drinking! U won't be able to get into a hospital!
"I'm lucky! [sic]"
Since news of her death broke on Monday her fans have flooded the post expressing their sadness.
One person commented: "It saddens me to learn you were struggling so much. You will be missed."
"May you be at peace now!" another posted.
Ashley was Playboy's Miss March in 2011.
She took her own life in her home last week.
Her sister Christy and twin brother Billy told TMZ that she left a suicide note at the scene.
