Let's make this birthday one to remember.

44 years old (Born on February 24, 1981)

Happy Birthday, Lleyton Glynn Hewitt! You've smashed records and aced your way through tennis history faster than opponents could shout "fault!" Becoming World No. 1 back on November 19, 2001 was just the warm-up set to an incredible career—winning epic rallies and capturing hearts with every fiery victory dance.

With a whopping collection of 28 ATP singles titles by 2013, you've clearly served up brilliance both inside the courts and in our memories. Today we celebrate you—not only as Australia’s favorite baseline battler—but also for consistently proving age is merely another number worth dominating! Game on champion; happy birthday mate!
