Nawww, this is just the cutest.

Guy Sebastian has posted an Instagram video of his two-and-a-half-year-old son Hudson saying the words every parent loves to hear: "I wuv you daddy".

"I could be having the worst day ever and hearing this will always make my heart melt," Guy wrote to his 142,000 Instagram followers.

The 32-year-old and his wife, Bringing Sexy Back stylist Jules Sebastian, are also proud parents to five-month-old son Archie.

But Guy's Instagram account isn't just cute baby vids and pics — in fact, he's quite the fan of cheesy internet memes. Yep, Guy really loves a dad joke.

Here are some of his faves… nice one, Papa Sebastian.
