The Voice coaches kick off new season with spine-tingling performance of Adele's 'Hello'

Well, here's a "hello" we won't forget anytime soon.

The Voice's Jessie J, Delta Goodrem, Joel and Benji Madden and new coach Ronan Keating busted out a cracking version of Adele's monster hit 'Hello' on Sunday night's season five premiere.

You could hear a pin drop as Jessie, who went to the BRIT School with Adele before they both hit the big time, sang those familiar words: "Hello, it's me." *TEAR*

It was a reconciliation of sorts between Jessie and Delta, who butted heads on last year's series.

But it was all back to business on episode one of the blind auditions, which featured everything from an architect's emotional song with a personal connection to Delta, to a lingerie store assistant's rendition of 'I Kissed a Girl' by Katy Perry.
