Proud father Ian raised his hand in the air before putting his arms around his daughter outside the family home in Bromley.
On Saturday, Raducanu became the first Briton to win a major title in 44 years and the first qualifier in history to win a grand slam.
Her parents – Romanian father Ian and Chinese mother Renee – had not been able to see their daughter triumph in person as they could not get the necessary visas to travel to New York.
A driving force behind teenage tennis star Raducanu said his parents were “proud and happy” after his win, adding: “These are my toughest critics and so hard to please – but I got them this time! “
Thanks to her victory, the teenager climbed 127 places in the world tennis rankings, from 150th to 23rd.
Her achievement was all the more remarkable as throughout her qualifying matches and the main draw on the way to the trophy lifting, she didn’t lose a single set.
After the New York tournament, the 18-year-old spent several days touring the city before returning home.
She made her Met Gala debut wearing a black and white Chanel ensemble and visited the New York Stock Exchange.
Raducanu’s success has garnered praise from around the world – including royalty, other sports stars and celebrities, with the Queen and Duchess of Cambridge among those congratulating the tennis star.
In a letter, the Queen wrote: “This is a remarkable achievement at such a young age, and a testament to your hard work and dedication. ”
