Last week it was Prince William and now Wallabies duo Will Genia and Bernard Foley have found themselves in the company of tennis royalty in London.
The ATP Tour finals are being held in London this week, featuring the world's highest-ranked players, as the Wallabies prepare for this weekend's clash with England.
Keen Roger Federer fans Genia and Foley hot-footed it from training on Thursday afternoon straight to the O2 Arena to watch the Swiss maestro in action.
The pair sat front row, along with TV survival guru Bear Grylls, as Federer fought back from a set down to beat Marin Cilic, 6-7, 6-4, 6-1 in their group match.
Federer is the biggest name left in the competition, with Novak Djokovic, Andy Murray and Stan Wawrinka all absentees and Rafael Nadal withdrawing earlier in the week.
They weren't just watching on, though - the pair were able to meet Federer post-match, quick to share the snaps on social media on Thursday night in London.
Responding to comments on his post, Genia said he was 'fangirling hard' and it was a 'dream come true' when he met the international tennis legend, after seeing him in the flesh for the very first time.
Genia has had a good run of meeting international sporting stars this year, in June part of a contingent that met Argentina football star Lionel Messi in Melbourne.
Foley and Genia will both start for the Wallabies against England on Saturday, hoping to buck a four-match losing streak against the old enemy.
