From Australia, France, China and South Korea, the best of the ballkids have come together for the annual squad photo as preparations for the Australian Open kick into high gear in Melbourne.
They were joined by some of the best players in women's tennis.
Former world number one Venus Williams shared some wisdom from her on court life.
"For me my biggest failures made me a champion. So, if you lose guess what that means you're pushing yourself and putting yourself in a position to win. Live your life with no regrets and leave it all on the court."
And where one sister goes, the other will follow.

Moments later, 22-time grand slam winner, and current world number two Serena Williams ducked in for a photo and an inspirational message.
"You know you guys are so important for the tournament and for the players I don't know if that is said enough. So I think it's really cool Venus and I are doing this today."
The competition to win an invite to the Australian Open is almost as hard for the ballkids as is it is for the players.
Don-gun Kim was chosen from 1,500 candidates in South Korea to be part of the country's delegation of just 20 ballkids.
The 13-year old says he's ecstatic to have made the cut.
"It is really excellent, it's such a glory to be here I am so happy. I've been watching tennis in Korea and my dad likes it too. I really like to be a ballkid."
14-year old Li Jingyi is one of six to have made it through the Chinese selection trials.
She says she came to Melbourne Park as a ballkid this year, but next year she hopes to return as a player.
"I want to be a tennis player, yep, and I want to be like Serena Williams."
The final ballkid squad is composed of 380 kids chosen from over 2,500 applicants.
The selection process has taken 12 months, and at each of the five stages the numbers are cut.
And the trials don't stop now.
The ballkids will continue to be tested to ensure only the best get selected for high profile matches on the main court - Rod Laver Arena.
Australian Open Tournament Director Craig Tiley says it's a necessary measure to maintain the grand slam's reputation as having the best ballkids in the world.
"It's a fairly rigorous process, you apply very early. The whole process take about a year. Then you go through trials, selection trials and you progress, you have several of those trials throughout the year."
It's a hefty time commitment for teenagers on their school vacation, but for Nicholas and Damien Sapounakis - one of four sets of twins - there is no place they'd rather be.
"It's a good experience just to be here. We usually come for the tennis anyway but to be here every day is just really good."
