Robbie, 44, tried to get the camera man to ignore Simon’s request as the X Factor judge said he wanted to speak on behalf of his contestant.
Shan had stopped her performance before even starting as she wanted to make a speech herself about the meaning behind the lyrics.
The contestant sang Sorry Seems To Be The Hardest Word by Elton John as her choice of song for guilty pleasure’s week.
Simon ordered Robbie to quieten down as he tried to locate a camera to speak to the ITV viewers at home.
Shan’s unusual take to start her performance seemed to worry some viewers at home, and they took to Twitter to voice concern.
One viewer wrote: “I thought Shan was going to break down into tears at the beginning #XFactor #TheXFactor #XFactor2018 #TheXFactor2018 #GuiltyPleasures.”
Last week, the contestant took on Imagine by John Lennon and received great comments for her performance from both the judges and the audience.
After the first live show, Shan has quickly become the bookies’ favourite to win the singing competition, meaning Simon could secure his second consecutive win.
Bookmakers OddsMonkey have put her at 7/4 to win this year’s series of X Factor.
Peter Watton, a spokesperson for OddsMonkey told Express.co.uk: “Shan was impressive, and it is no surprise to see her back at the head of the market along with Misunderstood and Brendan Murray.”
However, this could be a devastating blow for Ayda Field, 39, who could lose another one of her acts this weekend.
Ayda saw one of her Overs category, Olitunji Yearwood, sent home and another, Janice Robinson, in the bottom two.
After being saved by Simon, Janice is now set to leave the competition this weekend, with Peter adding: “Talking of attracting money in the betting market, Janice has been seen plenty of it – but for the wrong reasons.
“She is 6/4 favourite to be out, ahead of Giovanni and LMA Choir, who were both favourites to go in the opening week.”
Simon’s altercation with Robbie wasn’t the only swipe he faced in the second live show.
20-year-old Scarlett Lee had just performed her rendition of Always On My Mind by Elvis Presley when the judge applauded her for her efforts.
Last week, Simon was pleased per her vocal of Natural Woman by Aretha Franklin, however, seemed to think his act sounded like a club singer.
Dermot wasn’t going to let Simon forget about the comment and dealt the blow before speaking to Scarlett about the critiques.
He said: “Simon, it’s always nice to see you being a bit more supportive of your own acts.”
X Factor continues tomorrow night at 8pm on ITV.
