For some time now, 'X Factor' has discovered incredible talent as the seasons go by. Along the way, we've also seen some iconic judges join the panel so without further ado, here's our Top 5 best judges ever on 'X Factor'. [Take the poll below and let us know who's YOUR favorite]\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=bshwIHj6Bp0\n\n\n\n\n1. Sharon Osbourne\n\n\n\nSharon Osbourne: The x Factor Judge\n\n\n\nWe can't get enough of Sharon on the show and we already miss her! Sharon was by far one of the most charismatic judges ever to appear on the panel and was unique for her wit. Ms. Osbourne knew how to be fierce and put Simon in line at just the right moments. It has to be said that there's really no one, however hard the show tries, that can replace her! \n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=wBSGt4py75w\n (WATCH) The act that made Sharon Osbourne cry on The x Factor live shows \n\n\n\n2. Robbie Williams\n\n\n\n\n\n\n\nRobbie joined the panel in 2018 alongside his wife Ayda Fields (Want to know more about Ayday, here are 10 facts about her). Throughout the season, it was obvious that Mr. Williams is a true showman! He knows how to put on a show from the stage and from the judging desk. The former judge created such a strong bond with all his contestants during the live shows, despite missing a few episodes. We'd be thrilled to have him back. \n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=3vfLyXoUroo\nRobbie Williams forms a brand new group during the 'X Factor' Six Chair Challenge\n\n\n\n3. Simon Cowell\n\n\n\n\n\n\n\nIt wouldn't be right if we didn't include the X Factor boss himself, Simon Cowell. Simon's been on the show on and off since the beginning and we're so glad to see he's still at it. Known for his harsh criticisms and honest truths, Cowell knows a star when he sees one and therefore has been successful in creating some of the biggest artists in the world. \n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=sSOCIxu2FPI\n (WATCH) Simon Cowell's favorite auditions ever on the show\n\n\n\n\n\n\n\n4. Nicole Scherzinger \n\n\n\n\n\n\n\nNicole Scherzinger, what an icon! She brings the energy every time she's on the X Factor judges panel and is a powerhouse of a judge. Nicole is always the first to get out of her seat to encourage the contestants on stage and we can't get enough of it! Chemistry between the judges is vital, and it can be said that Scherzinger is a chemisrty machine. She creates chemistry with the contestants but also makes the panels she sits on work so well together! \n\n\n\nNicole Scherzinger also brought a fair share of flirtatious moments to the X Factor over the years. Most notably is her widely reported "romantic" relationship with 2016 winner Matt Terry. Although fans may argue wether these were real or just publicity stunts, one thing is certain, she has that special spice and she uses it .\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=mhzHeJN2egE\n (WATCH) A classic Nicole Scherzinger moment: storm off stage during Six Chair Challenge \n\n\n\nRELATED: Is Nicole Scherzinger the most underratted TV judge in the history of judges?
