Elizabeth Hart-Browne is alleged to have stabbed Mr Rayner three times with a kitchen knife
Elizabeth Hart-Browne stabbed Stephen Rayner three times with a kitchen knife as her two young children slept nearby, the jury was told.
Neighbours heard the couple rowing before she allegedly picked up a large, purple-handled knife and attacked him, the Old Bailey heard.
Blood pouring from his wounds, the court heard how 25-year-old Mr Rayner stumbled outside before collapsing.
Hart-Browne, 27, screamed: “He’s dead! He’s been stabbed!,” jurors were told.
Jurors heard how Hart-Browne phoned the police in tears
Witnesses saw her leaning over Mr Rayner’s body as he lay in a pool of blood outside their home in Acton, west London, the court heard.
Barefoot and wearing one earring, jurors were told how Hart-Browne was weeping when police and paramedics arrived.
Mr Rayner showed no signs of life, said Rosina Cottage QC, prosecuting.
Hart-Browne allegedly told officers: “I didn’t mean to do it. I’m so sorry. I have just killed the man I love.”
She denies murdering Mr Rayner on September 17, last year.

Hart-Brown claims he was “accidentally injured” after she grabbed the knife to defend herself, said Ms Cottage.
The couple, who slept in the living room of their flat, had been in a “volatile” relationship for six years, the court heard.
Ms Cottage told the jury: “It was on/off and occasionally there was a verbal and physical aggression on both sides.
“The rows appear to have been stimulated by allegations of infidelity against Stephen Rayner and jealousy and controlling behaviour by the defendant.
The court heard how their six-year relationship involved occasional verbal and physical aggression
“She didn’t trust him in relation to his behaviour with women, where he went or what he did because of infidelity in the past.
“In the days leading up to the events of September 17, the defendant and Stephen Rayner had been arguing about his behaviour and her jealousy.”
Hart-Browne accused Mr Rayner of lying and had gone to stay the night with a friend, jurors were told.
On the day he died, Mr Rayner took their son to watch Queens Park Rangers play football, the court heard.
Jurors were told how Hart-Browne, who worked at the Westfield shopping centre, went to a family party where she drank wine and champagne.
When she got home, her partner was lying in bed wearing a pair of shorts, the court heard.
Ms Cottage said: “She picked up a kitchen knife and stabbed him three times.
“The final injury was a deep wound to the neck which led to bleeding into the chest and then to his death.”
Tests showed she was twice over the drink drive limit, whereas her victim was sober, the court heard.
Ms Cottage said: “This level of alcohol would be expected to produce significant intoxication in the average drinker.
Hart-Browne claims she picked up the kitchen knife in self-defence
“It may well have influenced her temper and perhaps her decision making.”
Hart-Browne claims Mr Rayner was attacking her and she grabbed the weapon in self-defence, the jury was told.
Ms Cottage said: “The defendant says that she picked up a knife from the living room table to defend herself while she was being violently attacked and that during the struggle they stumbled and Stephen Rayner was accidentally injured.
“The prosecution say that she is lying and that she deliberately stabbed Stephen Rayner with it intending at least to cause him serious harm if not to kill him.”
After the death, Hart-Browne washed the knife and left it on the draining board behind baby bottles, the jury was told.
Questioned by detectives, Hart-Browne insisted she was not drunk when she arrived home, the court heard.
But tests showed she would have been twice the legal limit for driving, the court heard.
Mr Rayner subjected Hart-Browne to physical and mental abuse during their relationship, said James Scobie, QC, defending.
Mr Scobie read an emotional message Hart-Browne sent her lover in January last year.
She wrote: “All I have done is fall in love with you and you decided to hate me for it.
The court heard how Hart-Browne had accused Mr Rayner of infidelity
“Just realise what you’re doing. That’s all I want. Why can’t you change back?
"Back to the man who loved [my oldest child], me, who would do anything for us, who would hurt if I hurt.
“The man who didn’t abuse my self worth to make himself feel better. The man who made me happy. All I want from you is for you to love me.”
In the message, she claimed Mr Rayner called her “fat, ugly and thick.”
He also told her he enjoyed hitting and humiliating her, Hart-Browne wrote.
Mr Scobie asked: “Why would she stab gratuitously the man who she wanted to be a father to her children?
“That knife was not picked up for any other purpose than the history of violence towards her.
“She was emotionally dependant on the man she loved and the man she killed.”
The trial continues.
