Kobe Bryant has told his 13 million Facebook fans his visit to the Australian Olympic swimming team last week was "a great opportunity and honour".
The American basketball superstar wrote that he happened to be staying in the same hotel as the Aussies in Manchester and "couldn't resist the chance to watch them train".
"I loved the attention to detail they put into their training and the methodical approach they have," Bryant wrote.
He said of Stephanie Rice: "I was lucky ... I had the chance to see the best in the world prepare and she is FOCUSED."
And among so many sporting greats flocking to London in the lead-up to the opening ceremony this Saturday, the admiration was mutual.
"It was awesome to have him come to the pool just to watch us train. It was like we were doing time trials and everyone did their best swim in front of him," Rice told reporters.
She also tweeted: "Absolutely lovin being in the Olympic Village and seeing so many great athletes. 3 more days till Day 1 ... Can't wait to race!!"
Teammate Kenrick Monk said Bryant was very down to earth.
"He was really interested in what sort of work we were putting in and how we it all fitted in to place ahead of the Olympics," he told News Ltd.
Bryant, who has 13 million Facebook fans, posted a photo of himself with Rice, both sporting huge grins.
He reflected on the opportunity the Olympics offer to meet and study sporting greats.
"The Olympics for me is a great chance to learn from the (world's) best and figure out what makes them tick all while representing your country," Bryant said.
"What a great opportunity and honor."
