However, Jess needn’t have worried, as the voting was unanimous – with all the male contestants choosing the TV star for the role of Baby.
Speaking on behalf of the boys, Jamie Durie said: "We were all just so taken with all of your performances, they were absolutely mind blowing."
"The transformation from day one to now, has been phenomenal. This has been a very, very tough decision."
"But unfortunately there can only be one winner... and it's Jess! You were amazing."
Jess – who pipped fellow contestants Stephanie Rice, Anne Edmonds and Anna Heinrich to the post - will be the Baby to Hugh Sheridan’s Johnny.
"I'm so overwhelmed. It was the furthest thing from my mind that this would happen. I can't believe it."
