London (AFP) - Eugenie Bouchard admitted one of her character flaws is impatience but she was happy to wait "in awe" as Prince William and his wife Catherine passed by at Wimbledon.
The 20-year-old Canadian, widely expected to succeed Maria Sharapova as the multi-million dollar poster girl of women's tennis, made her first semi-final at the All England Club on Wednesday.
But her entrance on to Court One was delayed when security men ensured she and opponent Angelique Kerber stood to the side so that William and Kate could take their seats in the Centre Court Royal Box.
"It was funny, when we walked out at five to 1:00 from the members' locker room, all these security guards rushed over to us and were like, 'Nobody move'," said Bouchard.
"Move your bags to the side. There's some Royals coming through. We're like, okay, you know.
"So we were just waiting, and then suddenly William and Kate walk by to go on Centre Court. I was a little bit in awe. That was my Royal sighting of the day."
Bouchard has spent large parts of her post-match Wimbledon duties answering questions on the British royal family.
That is hardly surprising given that she and twin sister Beatrice were named after the daughters of Prince Andrew, the second son of Queen Elizabeth II.
Princess Beatrice was also in the Royal Box on Wednesday.
Beatrice Bouchard, who is six minutes older than her sister, meanwhile, was back home across the Atlantic where she is a university student.
"We are very opposite but very close at the same time," said the tennis-playing Bouchard.
"It's interesting, because I think her normal university life, I think that's really cool because I don't do it. She obviously thinks my job and what I do is insanely cool.
"So we keep in touch a lot and we're very close. She's a huge supporter of me. Same with me for her. I get on her about her grades and things like that."
Bouchard will rise into the top ten for the first time in her career next week after making her third semi-final at the majors in 2014.
Confident, photogenic and self-assured, the 20-year-old is perfect muse for Wimbledon especially after the demise of Sharapova, seven years her senior, in the fourth round.
Impatient she may be but she was happy not to show it when William and Kate breezed past.
"I was okay to wait that time. I just watched in awe," she said after her 6-3, 6-4 win over Kerber.
