Louis Walsh CONFIRMS Celebrity X Factor judges AND first All Stars contestants

It's X Factor - Sinitta HAS to be involved somehow! But she wouldn't be taking part as a contestant... Sinitta has spoken out about the possibility of being on the judging panel, telling Closer magazine, "There have been discussions, but I haven't signed a contract yet. I'd love to do it, though – Simon's switching up the formula this year so I'd love to be involved."

Reality queen GC is reportedly set to appear on the show, having been on pretty much every single other reality show there is! A source told the Daily Star, "We want big and exciting stars and The GC is popular and we reckon she makes entertaining viewing. Simon has handled many divas over the years with the likes of Sharon Osbourne and Mel B, so we reckon he will be able to deal with this Essex one." Plus there's the fact that Gemma wowed the audience of All Together Now recently when she sang 'Big Spender'!

Simon's pal and fellow Britain's Got Talent David Walliams has thrown his own hat into the ring, telling Radio Times that he's already "mentioned it" to Simon. "I cannot sing a note, so I'd fit in very well," he joked. "It would be fun. I don't know if it's going to happen but I would love to be on it. I've always loved The X Factor. I got to be on it last year with Robbie Williams at Judges' Houses so I would love to be on that stage, doing a duet with Wagner."

The Chase's Jenny Ryan is incredibly popular with viewers of the show, and actually has a wonderful singing voice - something she showed off for Let's Sing and Dance for Comic Relief last year with her fellow quizmasters. A source has said she could be the "dark horse" of this competition.

Of course, John Barrowman needs no introduction, and he never misses an opportunity to flaunt his incredible vocals. The West End star told Metro that he'd "love to do it", adding, "It's one of those things where if I'm asked I'd do it, like anything, I'd do it at the drop of a hat as long as I know I'm gonna have fun doing it."

You'd be forgiven for not recognising her name - but surely you remember the little girl with the incredible voice singing 'All I Want For Christmas Is You' in Love Actually? An insider revealed that show bosses wanted to keep the line-up "varied" and that Olivia would be a "great shout".

Former Strictly Come Dancing professional Brendan Cole is reportedly being eyed up by ITV bosses after his dramatic exit from the BBC show. An insider said, "Brendan is a big character and the bosses are sure that he will be a big draw for their audience. His Strictly fans aside, they are expecting people to tune in to see how his singing compares to his dancing." Brendan has showed off his vocal abilities before, singing with Beverley Knight on Just The Two Of Us in 2007.

TOWIE star Megan McKenna is already a singer in her own right, having released single 'High Heeled Shoes' last year. However, it looks as though Megan could be attempting to win over Simon once again, having previously auditioned on Britain's Got Talent in 2009 as part of girl band Harmony and on The X Factor in 2014 and 2015 as a solo artist. When asked on Loose Women, Megan was decidedly evasive, and said, "I'd seen the rumours as well. I mean, I love that show. But I don't know anything about that. But I do love that show, it's amazing."

Love Island 2018 alumni Zara McDermott, Wes Nelson, Samira Mighty and Eyal Booker are apparently joining forces to be a group on the show. Of course, Samira is a West End star and Eyal was previously in a pop band, and apparently the four of them have been "discussing songs" and are all "confident that they can hold a tune."
