Cape Town - It's been 15 years since stars Roger Federer from Switzerland and American Serena Williams held the winning trophies at Wimbledon, for the first time.
Little did the 21-year-olds know that it wouldn't be the last time that they'd be Wimbledon winners in the same year.
Last week Serena shared pictures on Instagram of her and Federer in 2003, 2009 and 2012 when they were also both Wimbledon champions.
Now, 15 years since their first win in 2003, the two will be back battling it out on Wimbledon's grass courts.

Federer is seeded first in the men's singles, while Williams is seeded 25th in the women's singles division, tournament organisers announced in a statement.
Federer has played in the Wimbledon final 11 times, and emerged the champion eight times.
He won the championship for five consecutive years - from 2003 until 2007 - and is also this year's defending champion.
Wiliams has played in the Wimbledon women's final nine times and since 2002 she's won seven times.
She lost to Russian player Maria Sharapova in 2004, and again in 2008 to her sister, Venus.
Last year Serena withdrew from the tournament due to her pregnancy. Her daughter, Alexis Olympia, was born in September.
Williams married Alexis Ohanian shortly thereafter in a glamorous event, only returning to tennis in the French Open earlier this year. However, she had to withdraw - due to injury - in the fourth round at Roland-Garros in Paris.
In an interview with the Wall Street Journal earlier this year, Federer said he considers Serena one of the world's best: "If not the greatest tennis players of all time".
