Emma Raducanu smiles as she dons a chunky blue sweater and jeans for casual stroll in London

British tennis sensation Emma Raducanu appeared to be having a business meeting on-the-move on Monday.

The US Open 2021 champ, 18, flashed a smile as she was snapped taking a stroll in London alongside her sports agent Chris Helliar.

Emma donned a blue roll-neck sweater in a chunky design, despite the clement September weather.

She added slim stonewashed jeans and white trainers to the look, perching a pair of vintage shades on her head.

She wore her raven locks sleekly around her shoulders and displayed a creamy visage of natural make-up.

She tied back her mane later on as she and Chris strolled along, both checking their phones – which are bound to be popping given the events of the past week.

The tennis sensation made sporting history by winning the US Open earlier this month – the first British woman to win a major title for 44 years since Virginia Wade lifted the Wimbledon trophy in 1977.

She is also the first qualifier in history to lift a grand slam.

The teenager has been heralded as a ‘sponsor’s dream’, and is on course to becoming the highest earning female sports star of all time.

It was also reported that she laid the groundwork for her potential earnings aged 17, registering Harbour 6 Limited to manage her finances.

Her return home to the UK comes after a whirlwind week following her incredible triumph in New York. 

Emma told reporters outside her home: ‘It’s a great feeling to be home. I’ve been away for seven weeks so it’s nice to be back. It was nice [to hug her parents]. Nice to see them again.’

The smiling tennis star also said she was looking forward to relaxing but hasn’t thought about any parties or reunions with friends.

She said: ‘I haven’t thought of anything [going forward]. I’m just enjoying it and relaxing and recovering. We will make some plans.’

 Emma told reporters outside her home last week: ‘It’s a great feeling to be home. I’ve been away for seven weeks so it’s nice to be back. It was nice [to hug her parents]. Nice to see them again’

Her proud father said he was relieved to have her home and happily hugged Emma as they posed for photographers outside the family property. 

The reunion comes after it emerged Emma trademarked her name within hours of her US Open win in her first steps to becoming the ‘first billion-dollar sports woman’. 

UK-based lawyer Anthony Brierley applied to safeguard the words ‘Emma Raducanu’, ‘Emma’ and ‘Raducanu’ shortly after the 18-year-old’s victory, reports The Sun.

Emma, whose parents both work in the City of London as currency market traders, has admitted to still being on ‘cloud nine’ after her stunning victory and plans a few days of rest before she is back playing tennis again.

However, she also shared her desire to get back on the court and is expected to appear at BNP Paribas Open in Indian Wells next month.

She said: ‘I have a few days’ rest and recovery (coming up), I think needed after the last seven weeks but then I am straight back to training and hungry to get better and come back out and play some more tournaments.’

The 18-year-old defeated Leylah Fernandez 6-4 6-3 at Arthur Ashe Stadium on Saturday to become Great Britain’s first female grand slam winner in 44 years.

It was only Raducanu’s second appearance at a major and the new world number 23 has made headlines across the globe, appeared on various TV channels in the United States and she also attended the Met Gala on Monday in a monochrome Chanel ensemble.

MailOnline also revealed she has been spending time with old friend and former British tennis protege Benjamin who is studying in New York. He was seen hugging her in front of one of her new Nike billboards in Times Square.

Success: Emma is the first British woman to win the US Open in singles since Virginia Wade in 1968 and is currently the top ranked British player

On Tuesday she ticked off another long-term aspiration when she visited Wall Street. ‘I am on cloud nine but so excited to be here on New York Stock Exchange. It was one of the places on my bucket list before leaving New York and I’m just so excited and grateful to everyone who made this possible,’ Raducanu told CNBC’s Closing Bell programme.

Jonathan Shalit, who landed lucrative deals for Olympic boxer Nicola Adams and singer and TV host Myleene Klass, says Emma could become the first billion dollar female sports star.

The chairman of InterTalent predicts Emma’s off court earnings will swiftly surpass those of Japanese tennis star Naomi Osaka and US legend Serena Williams – the world’s two highest paid female athletes last year.
