The model girlfriend of Jerome Boateng killed herself on her son’s sixth birthday just a week after splitting up from the German footballer, it has been revealed.
Kasia Lenhardt, 25, was found dead at a luxury apartment thought to belong to Boateng in Berlin’s upmarket Charlottenborg neighbourhood on Tuesday night by police, who said the death is not being treated as suspicious.
A friend of the model told MailOnline: ‘Yesterday was her son Noah’s birthday. Kasia was at home on her own. A member of her family called the police because they could not get hold of her and they were worried.
‘She died a week after Jerome gave an interview in which he said their relationship was over. He said some really nasty things about Kasia. She was very upset by it.’
Her death was confirmed Wednesday by model friend Sara Kulka on Wednesday who paid tribute in a cryptic Instagram post that said: ‘I hope the truth comes out. I know how much you wished it would.’
Kasia had been dating 32-year-old Boateng for 15 months before their relationship imploded on February 2 amid a vicious fight that saw the couple use social media and the press to exchange blows.
Boateng had accused Kasia of sabotaging his relationship with ex-girlfriend Rebecca and his family before they started dating, and of blackmailing him into staying with her.
Meanwhile Kasia – who had the footballer’s name tattooed on her ribcage – branded her ex ‘the devil’ and vowed to ‘speak up’ and ‘fight back’ once she had recovered from the break-up.
Just hours before she was found dead, Kasia had posted to Instagram talking about a ‘new chapter’ in her life.

Boateng, who now plays for Bayern Munich, was the first to announce the split after Kasia wrote off his Mini in a crash in Berlin on January 5, with German media reporting that she was over the alcohol limit.
Announcing the split, the sportsman said he was going to ‘take responsibility and act in the interests of [my] family’ while apologising ‘to everyone I’ve hurt especially with my ex-girlfriend and our children’.
In an interview with German newspaper Bild, Boateng then accused Kasia of blackmailing him with fake accusations of domestic abuse, while saying she has a ‘massive’ problem with alcohol.
He admitted cheating on ex Rebecca Silvera with Kasia, but said she was also controlling and abusive.
He said: ‘Kasia became my girlfriend by breaking the relationship with my ex-girlfriend Rebecca and my family and blackmailing me.
‘So I decided to stick with Kasia and try to make it work. Even making the relationship with her public was due to pressure from Kasia to do so. It wasn’t mine.
‘During our relationship, Kasia often threatened to destroy me. She threatened to ruin my career and even try to make me lose my children.
‘Kasia said she would do so by accusing me of beating her. She knew that my children’s mother accused me of the same thing and that we have a lawsuit over it.
‘Kasia contacted my children’s mother and said she would help her in court. Everything just to destroy me.’
He even went so far as to claim that the model used fake social media profiles to attack him and ‘spread lies’.
‘I hope she gets help that she urgently needs,’ he added.
But Kasia hit back, saying she had in fact ended the relationship because of Boateng’s ‘lies and constant infidelity’.
In a final parting shot, Kasia branded Boateng ‘the devil’ and said: ‘I will definitely speak up, but I have to collect myself. Please give me time.
‘I will fight back! Because I’ve never been so deceived, used and lied to. Give me a moment.’
News of Kasia’s death was confirmed by fellow model Sara Kulka, who uploaded a photo of the pair on Instagram.
Alongside it, she wrote: ‘Rest in peace. You wonderful person, I miss you and would have loved to say goodbye.
‘I hope you find your peace now and I hope the truth comes out now, I know how much you wished it would.
‘I will never forget you, I don’t know anyone who could laugh like you. I send a lot of strength to the family.’
As the news of Kasia’s death broke Boateng was in Qatar playing for Bayern in the Fifa Club World cup – with reports suggesting he is now flying back to Munich for ‘personal reasons’.

Kasia rose to prominence on TV show Germany’s Next Top Model where she appeared in 2012, placing fourth in the competition.
She leaves behind a son, Noah, who is thought to be five years old and was born to a previous partner that she split from three years ago.
A Berlin police spokesman said: ‘Yesterday at around 8.30 p.m. there was a police operation in Charlottenburg on suspicion of suicide.
‘A lifeless person was found in the home. There are no indications of third-party involvement.’
MailOnline has reached out to representatives for Boateng for comment, but had not heard back at the time of publication. Fab4Media, which represents Kasia, put out a statement on Instagram which reads: ‘We are deeply shocked and are mourning with Kasia’s family.’
Boateng has a long and troubled history with the women in his life, and is currently embroiled in a lawsuit with Sherin Senler – the mother of his twin daughters – over claims he assaulted her in 2018.
The footballer is alleged to have thrown a small glass candle holder at her while on holiday, which his lawyers say is based on unproven third-party allegations.
Boateng and Senler began dating in 2007 but have had a stormy relationship which has seen them separate on numerous occasions amid allegations of repeated cheating, including with model Gina-Lisa Lohfink – though both parties have denied this.
The pair’s break up in 2011 – the same year twins Soley and Lamia were born – was so acrimonious that they were said to have only communicated through their lawyers.
Boateng and Senler, a former fashion student, rekindled their love in 2013 and got engaged the following year but are understood to have split again following the alleged assault in 2018.

The footballer was then involved in a relationship with Jamaican fashion model Rebecca Silvera, though it is unclear when exactly they started dating.
The pair dated until October 2019, when Boateng was first pictured with Kasia during a visit to New York.
Kasia confirmed their relationship was genuine in follow-up Instagram posts in December and on Valentine’s Day the following year, describing Boateng as ‘my love’.
But the romance headed into trouble in December last year as Rebecca took to Instagram to accuse Kasia of stealing Boateng from her by copying and manipulating her.
Boateng then split off from Kasia earlier this month, apologising to Rebecca and his family and saying it is ‘time to take responsibility’.
Kasia subsequently accused Boateng of ‘continuous infidelity’, though she did not reveal who the alleged trysts had been with.
Police said they were called to an apartment block in Berlin at 8.30pm on Tuesday to reports of a suicide, and found a dead body (pictured, the apartment)
