The 18-year-old’s death is being investigated by the local coroner after she tweeted the night before that she was missing her best friend Kyleigh, who passed away on October 31.

At the time of Kyleigh’s death, local media focused on the rise of bullying in the town of Perry, with schools offering counselling to all students.

In the Sunday night post, Lexi wrote: “I miss u. I would do anything to go on a cig ride with kyliegh rn.”

An hour later, she posted her final tweet: "Never been like this before.”

Lexi’s mother Amber starred in the eighth series of Big Brother’s US version in 2007.

She gained notoriety for her frequent tearful outbursts as she regularly clashed with fellow housemate Dick Donato.

It earned the reality star the nickname “whamber” by viewers.

During her time in the Big Brother house, Amber regularly spoke of her daughter.

Lexi is tragically the fifth teenager to die in a suspected suicide in the past six months.

Bizarrely, just two days before her death, Lexi shared a YouTube video by suicide prevention expert Jeff Yalden.

On hearing of Lexi’s death, a friend commented on the post: “So sad you were so alone.

"Man, this just hit me hard. We used to play together when we were kids. It's sad that I'll never be able to see you again. I hope you're happier where you are."
