The loved-up pair, who have been together for more than three years, are currently traveling through Italy and France together and have been posting many adorable snaps!
But, it's one photo that has everyone talking.
'We enjoyed the sunshine in Venice while getting totally, happily lost amongst the colourful buildings and winding water,' the 19-year-old captioned on an Instagram Boomerang. 'This was a magical day.'
In the short clip the couple are smiling from ear-to-ear and Bindi is seen sporting a ring on THAT finger.
'Did I notice a ring on her left hand?' one commenter wrote.
Another added, 'Did they get engaged and I missed it?'
Irwin and 20-year-old Powell first met in November 2013 while Chandler was visiting Australia Zoo with his family.
'I was there holding my echidna and was like, oh I'll give this wakeboarder a tour,' Bindi told Today. 'And I met him and his family and went gee, he's not bad, is he?'
Powell then later wrote to Bindi's mother Terri and asked if he could 'stay in touch' with her daughter.
So happy for these two!
