Let's make this birthday one to remember.

46 years old (Born on March 19, 1979)

Happy Birthday, Ivan Ljubicic! You're officially older—but let's be honest, you've always been ace-ing milestones with style. From blasting serves and clinching that memorable Olympic bronze in Athens, to racking up 10 ATP singles titles—clearly excellence is served daily in your world.

Even though you're not smashing aces on tour courts these days, you still show us all how it's done off-court. May your birthday celebrations today reflect just how legendary you are—and hopefully fewer tie-breakers than some of those nail-biting matches from your stellar career!

Cheers to another year packed full of laughter, success and grand slam-level adventures!
