Last night their dad played the final game of his professional tennis career, on home turf, at the Australian Open in Melbourne.

But today we’re calling it: Mia, Cruz and Ava Hewitt, the 34-year-old’s three gorgeous children with wife Bec, are the ones with serious star power.

From singing “You’re the greatest dad, we’re so proud of you…” in a pre-match recording on Channel 7, to seven-year-old Cruz blowing kisses to his dad between points they are point blank cute. Check this out …

(Post continues after video)

After game, set, match was called to his well-deserved Spanish opponent, David Ferrer, Hewitt’s children joined him on court where they received big kisses from their proud – sweaty – dad. And as the family made their way towards the locker room post-match, the kids chattered away, completely oblivious to the night’s significance.

They took all the hysteria in the stride. Crowds? No problem. Cameras? Fine. Deafening cheers? Ummm – for us or dad?

Supporting Lleyton from the sidelines around the world has been part of life for the blond trio. And we think they’re gorgeous, so we’ve compiled some of Mia, Cruz and Ava’s cutest moments.

You’re welcome.
