‘X Factor Australia’ 2016 grand finals news: Fans wonder whether Robbie Williams would pull another breast-nuzzling stunt in the finale

As fans anticipate who’s going to take the “X Factor Australia” 2016 title, they are also excited to watch live performances from guest acts at the grand finals week, led by British musician Robbie Williams.

The 42-year-old “Love My Life” singer grabbed headlines this week when he buried his face in German TV presenter Barbara Schöneberger’s chest at Berlin’s Bambi Awards. Robbie, who took home the Music International Award, shocked everyone when he nuzzled the host’s breasts after saying, “Lovely to see those.” Prior to performing his latest hit, he also unzipped his fly on stage, according to a report by The Sun.

It would be interesting to see whether Robbie would do a controversial act as he takes the “X Factor Australia” stage in grand finals week. He is set to perform live, along with Charli XCX, Tori Kelly, James Arthur, Tove Lo and Jessica Mauboy.

In another star-studded evening, the “X Factor Australia” 2016 grand finalists will sing their hearts out for the last time to get this year’s title. Isaiah Firebrace, Vlado Saric, Davey Foder and Amalia Foy will engage in a four-way battle on Sunday, before the exciting announcement of the winner on Monday.

On its official web site, “X Factor Australia” published the top 4 form guide to help fans determine the chances of each finalist. Isaiah, 16, is dubbed the country boy whose voice is full of soul. His defining moment in the competition, according to the site, was when he sang Sam Cooke’s “A Change Is Gonna Come.” While the young singer is definitely a crowd-pleaser, he gets easily distracted, according to the site.

Amalia, Isaiah’s fellow act from Adam Lambert’s Under 22s category, also made it to the “X Factor Australia” 2016 grand finals. From the start, the 15-year-old schoolgirl made her mark with her cover of “Let Her Go” by the Passengers. She continued moving the audience and judges with her distinct voice, but as Mel B put it, she gets a bit boring on stage.

Speaking of Mel B, her lone Underdog act in the finals is 17-year-old heartthrob Vlado. Even before the grand finals, he got the bragging rights of being named Spotify’s most streamed “X Factor Australia” finalist.

However, he lets his emotions overwhelm him, which could affect his performance.

From three young acts, the last finalist may be considered this year’s dark horse. Davey Foder, from Guy Sebastian’s Over 22s, set the stage on fire with his rendition of “Working Class Man.” The 34-year-old crooner may play the age card by putting genuine emotion on his songs. Despite being the oldest contestant, Davey sometimes appear not too confident with himself while performing on stage.
