This year we've seen Simon make some big changes to the judging lineups on his most popular talent shows. From Alesha Dixon making the move to 'America's Got Talent' to the long time legend, Louis Walsh returning to this year's 'X Factor: Celebrity' but Simon's latest change for 'All Stars' may be his biggest yet...\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=khL3Ymy18mU\n Ben Foden, Levi Davis & Thom Evans are known for their fantastic rugby talent, but not singing! Together this trio perform on X Factor: Celebrity as Try Star and knocked Judges, Simon Cowell, Nichole Scherzinger and Louis Walsh off their feet with their epic cover of Blackstreet's 'No Diggity'!\n\n\n\nPaula Abdul is joining the all new lineup\n\n\n\nPaula is an all time favourite when it comes to talent shows and having her back behind the judging panel alongside Simon is enough to warm our hearts! It's also been eight years since they have both appeared on screen together, so let's hope their chemistry is just as good as it was back in the American Idol days. Joining them both is judge Louis Walsh, we can't say that wasn't expected!\n\n\n\nThe original 'American Idol' judges from Season 1 (Simon Cowell, Randy Jackson & Paula Abdul)\n\n\n\nBrand new location for X Factor: All Stars\n\n\n\nIt has also been announced that after huge spending on the celebrity version of the show, it will be filmed in a different location. For the first time ever it is being filmed from Birmingham, England. An insider from the show said, \u201cThe locals will get quite the shock when they see stars like Paula Abdul walking around and it\u2019ll probably be a culture shock for those coming from abroad.\u201d Birmingham isn't exactly a city known for showbiz and glamour so it'll take some time for Paula to settle in! \n\n\n\nWho are the 'All Star' contestants?\n\n\n\nThe full line up has not been fully released. A few big names have already been confirmed however, with artists such as Leona Lewis, James Arthur and Fleur East set to return. It's also likely that X Factor contestants from across the globe will also take part, similar to how 'The Champions' version of both AGT and BGT played out.\n\n\n\nLeona Lewis, won the X Factor in 2006 and is set to return for All Stars later this year\n\n\n\nWhen will the 'All Star' spin off show begin?\n\n\n\nThe show is set to air around November time on the lead up to Christmas. It's been an X Factor tradition for quite some time, so by the time it comes round to the final and the winner's single is out, it'll release just in time for the festive season! Winners singles in the past have included Alexandra Burke's 'Hallelujah' which across all platforms graced 1.39 million sales.
