According to local reports, the emergency services were called to Bobbi and Nick's home in Roswell Georgia at 10.25am on Saturday.

In a statement the Roswell Police Department said: 'Her husband and a friend located her in a bath tub this morning and she was unresponsive. 

'He started CPR and a police officer took over life-saving measures until an ambulance arrived.'

Lisa Holland of the RPD told People: 'Obviously we all know her mom died this very same way.'

Bobbi - the daughter of soul singer Bobby Brown - was pictured being wheeled out of the house on a stretcher. 

She appeared to be still unconscious and slumped over as paramedics lifted her into an ambulance. 

The unresponsive reality TV star was immediately transferred to North Fulton Hospital where she is still being treated in ICU, according to TMZ who describe her current condition as stable.

It is as yet unclear what caused her collapse.

Whitney Houston died on February 11th, 2012.

She was due to attend a pre Grammy Awards party when her lifeless body was discovered in a bath tub in a hotel room .

The Los Angeles County coroner’s office later confirmed the ‘I Will Always Love You’ hitmaker passed away as a result of drowning and "effects of atherosclerotic heart disease and cocaine use".

The cause of Bobbi’s incident is currently unknown, but local police are investigating the situation at her home while she recovers in hospital.

A recent Lifetime biopic of Whitney focused heavily on her drug use, received mixed reviews from viewers.

Bobbi did not comment on the movie after it aired earlier this month, although she had expressed her displeasure in advance.

Her grandmother Cissy was the most outspoken, angrily objecting to the movie even being made.

'Lifetime has chosen to go ahead with the movie about Whitney in spite of my family's objections,' the bereaved mother said in a statement to Entertainment Tonight in June.

'No one connected with this movie knew Whitney or anything about her relationship with Bobby.'

After her mother's death, Bobbi began a relationship with Nick who was described as like being a brother to her as she grew up.

The couple married in January 2014 but faced criticism after it emerged they had shared a home since before they were teens.

But they have insisted they are not blood related and are not even connected in any family way as Gordon was never adopted by Houston.

In late January Nick told Extra the jabs 'put a fire in us' and added: 'The critics can say whatever they want to say… it's like we have a force field and that s**t's just bouncing off of it.'

The two became friends when Whitney asked Nick, who was going through a rough time, to move in with them when he was only 12 years old.

But the relationship heightened a rift between her and her grandmother, Cissy who she fell out with when the matriach announced plans to write a book about her tragic daughter's life.

And in July 2013, Cissy penned an open letter to her granddaughter airing her concerns about her well-being.

She wrote: Krissi, all I want for you is your good health and your happiness.

'Do I want you to get married in the near future? No, I don't. I think you're too young and I wish you'd wait.

'But that's because I'm Grandma," she continues. 'I'm supposed to worry about you. I'm supposed to wonder if Nick or ANY man is good enough for you, My Baby's Baby.'

The young woman has long been the subject of rumours as to her alleged use of drugs.

In March 2011 Bobbi Kristina took to Twitter to deny claims she had checked into rehab after pictures surfaced that allegedly showed her snorting lines of cocaine.

At the time her mother was said to have desperately pushed the teenager to seek treatment soon after, with no success.

'Excuse me,' Bobbi Kristina tweeted, 'but I’d like to say that I am NOT going to rehab? I’m perfectly healthy and I am not addicted to anything but life.'

The National Enquirer, which first published the scandalous pictures, reported that Whitney had attempted an intervention of sorts.

Further pictures published by the tabloid in March 2012 shortly after Whitney's death showed Bobbi apparently using a three-foot bong to smoke marijuana.
