Former Wimbledon champion Boris Becker has fuelled speculation he’s fallen out with his daughter Anna Ermakova, after he failed to acknowledge her 25th birthday last week.

Model Anna was infamously conceived on the staircase of Nobu in London when then-married Boris, 56, enjoyed a spontaneous tryst with Angela Ermakova.

She shared pictures of her birthday celebrations to Instagram on Saturday, but Boris has neither liked nor commented on her post despite being active on social media every day since.

It’s the latest sign that Boris could have fallen out with his daughter, to whom he had been growing close in recent years.

Representatives for Boris and Anna both declined to comment when approached by MailOnline.

Six months ago, Anna was excluded from his third wedding to Lilian de Carvalho Monteiro, 33, in Monaco.

His eldest sons, Noah, 31, and Elias, 25, by his first wife, Barbara, were present – and reportedly the only children of his that he invited. 

Rumours of a rift between Boris and Anna have swirled since, marking a departure from their previously happy relationship.

In 2023, the German tennis star shared a very loving message to her on Instagram on her birthday. 

The year before that, Anna voiced concerns when he was jailed following a bankruptcy scam.

‘I will support him and I will visit him whenever I can,’ she said at the time. ‘I hope that will help him a little to get through the time.’

Six-time Grand Slam winner Boris, who earned £35m during his illustrious tennis career, was jailed for 30 months after a jury found that he hid millions of pounds’ worth of ᴀssets to avoid paying his debts.

Anna celebrated her birthday with friends at KOKO in Camden at the weekend, followed by a separate night out for mum Angela’s birthday at Annabel’s in Mayfair – just round the corner from the Nobu Park Lane branch where she was conceived.

In one of the pH๏τos she shared, aspiring singer Anna, a former winner of TV’s Let’s Dance – Germany’s equivalent of Strictly Come Dancing – looked glamorous in a figure-hugging metallic silver dress.

Friends who were absent on the day – including Strictly Come Dancing judge Motsi Mabusi and Elizabeth Hurley’s son Damian – commented and wished her happy birthday.

Boris did not engage, but on the same day he posted a video of a recent interview he did to his Instagram.

The following day, he shared an Instagram Story linking to the new hi Netflix series, Adolescence.

In contrast, Anna’s mother Angela shared a gushing tribute to mark her birthday, writing: ‘Happy birthday Anna… Years pᴀss by but I always remember giving birth to my one and only baby’

An insider said: ‘It’s a really stark change to his behaviour in recent years. He’s posted on her birthday before, and he used to like and comment on her pictures, so his silence is very noticeable.’

In the social media post that Boris shared on Anna’s birthday in 2023, he wrote: ‘I wish my beautiful daughter only the very best on her special day. I couldn’t be more proud of the woman she is becoming in front of our eyes! Love.’

In contrast, Anna’s mother Angela shared a gushing tribute to mark her birthday, writing: ‘Happy birthday Anna… Years pᴀss by but I always remember giving birth to my one and only baby. 

‘The umbilical cord is cut, but spiritual connection last forever – from here to eternity and back – the unconditional love never ends as time and space can’t constrict it … the mother-daughter bond is one of a kind that can’t be compared to other emotions and withstands all challenges that you go through in life.’
