Bindi Irwin's boyfriend and brother sing Adele's 'Hello'

Bindi Irwin has shared an adorable video to her Instagram showing her boyfriend, Chandler Powell, and her brother, Bob, singing along to Adele's 'Hello'.

Well... kind of singing.

The cute duo - who look to have a pretty rad bromance going on - can be seen looking into each others eyes as they totally own the power balled.

Ok, so they might be miming, but they're so darn good that even Marcel Marceau would be jealous.

A cheeky Bindi, who is sitting in the front seat of the car, can be seen giggling as she sneakily films the pair.

Bindi uploaded the video to Instagram with the caption: "When your little brother and your boyfriend decide that Adele is always a good idea. In the back of a convertible. In Hawaii.

"Also, thanks to Chandler's older brother for driving and laughing along with me on this... #LittleBrothers #CouldntResistPosting @chandlerpowell but you and Robert honestly bring me so much joy! I think I laughed for a good 20 minutes at this one."
