The great and good congratulated the legendary Rod Laver as he celebrated his 80th birthday on Thursday.
Eleven-time grand slam champion Laver toasted the landmark by sampling a beer from a glass with 'Cheers & Beers to 80 years' printed on the side.
The esteemed Australian tweeted: "Thank you everyone for the birthday wishes.
"I am very grateful to have such great family, friends and those I don't personally know, but feel like I do when I read your comments. I'm a lucky guy."
Boris Becker, Kim Clijsters and Martina Navratilova were among the fellow tennis stars to pay tribute to Laver on a special occasion for an icon who completed a calendar Grand Slam in 1969.
A day after Roger Federer turned 37, Becker tweeted: "There is something about birthdays in August when u play tennis ...@rodlaver turns 80 today!!! Congratulations to arguably the GOAT of our sport (we may ask @rogerfederer @RafaelNadal about it) @ATPWorldTour."
Clijsters posted: "Happy birthday to One of the kindest people I know! @rodlaver hope you had a wonderful day."
Navratilova tweeted: "Happy birthday Rocket!!!"
