On Sunday night's The Voice Australia grand finale, the English singer and songwriter Jessie J and Delta Goodrem put an end to their feud, as both of them embraced the other warmly on stage, right after the announcement of the grand winner, Ellie Drennan.

The conflict  between the two coaches started, early on the season when Jessie convinced contestant Joe Moore to side with Joel and Benji Madden instead of Delta.

It was the Australian singer-songwriter and actress Delta Goodrem who made the first move, after the Price Tag singer revealed earlier in the event that her 'enjoying it' face was actually a scowl , Jessie J explained that her facial expression is often misinterpreted and has drawn criticisms even from social media.

Jessie J said, "It's all real, we have heated moments," she also added, "It is what it is, people are always going to make a thing of two women, me and Delta are very strong women. And we get on really well but we debate too and we both have very strong opinions and I think it's really cool for people to see that not everyone is the same."

Then things got even heated up between Jessie J and Delta Goodrem, when the coaches again disagreed about their comments over Queensland singer teacher Tamara Callaghan. But all that is now "water under the bridge."

16 year old Ellie Drennan, the grand winner of The Voice Australia, is the youngest ever to win the reality show. Her winnings include a recording contract with Universal Music Australia, $100,000 cash and a new car, the Ford Kuga Titanium. 

She is coach Jessie's first victory on the reality singing show.

Jessie J said, "I'm all about tough love, I've held Ellie's hand this whole time but I can't be here all the time, I have to go do my career and Ellie has to survive on her own," Jessie J added, "I'm a phone call away, I'm a WhatsApps away, I'll always be here for advice, I've always said that to you, but this is it now, big girl world."
