British tennis player Cameron Norrie secured his place in the final four of Wimbledon after a dramatic five-set thriller.
He was cheered on by his parents David and Helen, who have come over from the family home in New Zealand to support their 26-year-old son.
Prince William and Kate, the Duke and Duchess of Cambridge, were also cheering from the crowed during his victory over Belgian David Goffin.
Also in the SW19 crowd for the quarter-final on Tuesday was his girlfriend Louise Jacobi.
Here is what we know about the British number one’s biggest fan.
Who is Cameron Norrie's girlfriend Louise Jacobi?
American Louise Jacobi is a professional and creative graphic, textile and interior designer, according to her LinkedIn page.
She lists herself as the co-founder of Studio Virgo, a luxury fashion and home accessories company based in California.
Louise has extensive New York-based career experience and cites having studied at the University of Michigan, gaining a degree in design.
On her education resume is also Central Saint Martin’s London Arts school - a potential hint to where she might have met her tennis ace boyfriend.
How long has Cameron Norrie dated Louise Jacobi?
The first posts on Louise’s Instagram with Norrie appear to be from January 2020.
It has been suggested they might have been going out longer than that, with reports stating that they kept their relationship private for a number of years.
It is not known when they met, but Louise is known to spend time at the world no. 12 seed's flat in East Putney, an area of south-west London not far from the courts of Wimbledon.
The pair are even known to have the odd playful row in the kitchen, according to Norrie.
In an interview with The Times discussing his pre-grand slam diet, the South African-born athlete said: “We get into arguments when we cook. Because Louise always wants to follow recipes to the letter while I prefer to wing it and experiment a bit.”
During author Simon Mills’ time with the couple for his Times article, he recorded how Louise “patiently read” the menu off her phone while also keeping an eye on the golf coverage on the TV, suggesting she may have sporting interests outside of tennis.
The couple regularly share snaps of themselves together on social media, including on holiday, celebrating the recent Platinum Jubilee in Blighty and at court side together.
In a picture from May 2020 after Norrie won the Lyon Open, Jacobi posted on Instagram: “He’s bringing home another title!”
