Michael Jordan's appearance at the US Open to watch Roger Federer in action - in a pair of trainers featuring both men's signature logos, no less - provided further proof that tennis players make the best celebrity buddies.
Eugenie Bouchard and Jim Parsons
Yep, Mr Million-Dollars-an-Episode himself, Sheldon from The Big Bang Theory. Bouchard is a huge fan of the show and contacted Parsons via his agent to invite him to SW19 to watch her play. A tennis fanatic already, Parsons took her up on the offer and stayed for the entire tournament as the Canadian 20-year-old reached the final.
She even posted a picture of her Sheldon stress doll after being upset by Shelby Rogers in Montreal:
Roger Federer and Anna Wintour
MJ wasn't the only star turn in Federer's corner at the US Open. Anna Wintour, the editor of US Vogue, is something of a staple ingredient when it comes to watching Roger do his thing of an evening on Arthur Ashe over the years.
Wintour, who plays herself at 5.45am each morning, has been on hand to offer Federer style advice over the years, the 17-time grand slam champion regularly asking for sartorial advice ahead of photo shoots.
Serena Williams and Michelle Obama
The First Lady of tennis played in front of the First Lady of the free world during the gold medal match at London 2012, but Serena Williams' relationship with Michelle Obama goes beyond her Olympic triumph at Wimbledon.
"She's so cool," said Williams, who is on first name terms with the US President's wife. "I've met her several times. I feel comfortable saying 'Michelle' and I think she wants the people to feel that way."
Williams was also on hand to take part in Obama's 'Let's Move' campaign for active schoolkids, joining quarterback Colin Kaepernick, gymnasts Gabby Douglas and Dominique Dawes, track and field athletes Allyson Felix and Ashton Eaton and former NFL and MLB star Bo Jackson.
Andy Murray and Sir Sean Connery
Scotland Forever? The double grand slam champion from Dumblane has drawn rare public appearances from the 007 star for the past two years - first alongside fellow legendary Scot Sir Alex Ferguson in 2012 as Murray worked his way towards his first grand slam in New York, before returning solo in 2013 to see the defending champion defeated by Stan Wawrinka.
You might say the pair have formed a strong - pause for comic effect - Bond. I thank you.
Victoria Azarenka and Redfoo
Ah, young love - kinda. Azarenka, 24, and LMFAO frontman Redfoo, 38, were together for two years before the couple split shortly before Wimbledon. Redfoo admits he still follows Azarenka's results and even penned a love song for the former Australian Open champion.
"She has an amazing career and opportunity to be the next greatest women's tennis player ever," Redfoo said in June. "If Serena [Williams] is the greatest, I think she has the talent and the work ethic to be the next best."
Rafael Nadal and Pau Gasol
Rafael Nadal may be a Spanish sporting giant in the figurative sense, but Pau Gasol fits the description literally. The Chicago Bulls Centre was in Nadal's box for his 2012 French Open victory over Novak Djokovic, and the duo shared a touching moment as Rafa celebrated his seventh victory at the year's second slam.
Gasol returned in 2013 to see Nadal beat compatriot David Ferrer, and the pair met up once more for dinner in California when Nadal was in town for the year's first Masters 1000 event at Indian Wells.
