Robert Irwin shared an adorable tribute to his sister Bindi's daughter Grace Warrior on Saturday in honour of 'May the Fourth' - a day celebrated by Star Wars fans. 

Posting to Instagram, the I'm A Celebrity host, 20, shared a photo of the three-year-old posing triumphantly on a beach with her arms raised towards the sky. 

The photo was edited to include iconic Star Wars imagery, including lightning bolts that dramatically struck the ground around her. 

The silhouette of the Death Star also loomed ominously in the backdrop, while fans also noticed TIE fighters and the beloved BB-8 droid enhancing the sci-fi aesthetic. 

A utility belt was edited around the youngsters waist, complete with a lightsaber hanging from the side.  

'Grace. Grace Skywalker,' he hilariously captioned the post.  

The post comes weeks after Robert was honoured with a special tribute off the back of his hosting success on I'm A Celebrity ... Get Me Out of Here! Australia. 

'Hey guys, I've got some really exciting news. A brand new species of snail that has just been discovered has been named after me,' the Wildlife Warrior began in a video shared to social media.

'This is the Robert Irwin Banded Snail, have a look at him, isn't he cute?' he continued as an image of the creature appeared on screen.

'Some of the world's leading snail scientists, or malacologists as they're officially known, found this little bloke in southeast Queensland.'

'Previously unknown to science and they decided to name him [after me]. What an honour.'

Robert added that the tribute was 'particularly meaningful' to him because of his conservation work involving habitat protection.

It comes just after the finale of the 2024 season of I'm A Celebrity, where Robert was praised for his co-hosting role with Julia Morris, after Dr Chris Brown's departure from the show.
