For whatever reason?
They don't have to be that similar but for what 'vibe' do they give you? For me

Che - Sam Smith
Mason - Chris Brown
Lauren - Kelly Clarkson
Monica - Amy Winehouse
Anton - Stevie Wonder
Bupsi - Sunitta
Max - George Ezra

Monica reminds me of Ruth Lorenzo from a few years ago, only she is much better.

Mason - one of the thousand generic singer and dancing pop guys
4th Impact - one of those Asian pop girl groups...there are many of them. ...
Louisa - Joss Stone maybe. ..who knows? ??
Kiera - a extremely basic Rihanna...

The rest don't remind me of anyone...

Anton - a singer who is from the 1970's...

Not a singing artist but a lookalike. Lauren so much looks like the Geordie Girl on Gogglebox

Mason - Jay Sean or Colby O'Donis

Scarlett

Reggie N Bollie- The Beatles,but obviously a lot better.

*takes Simon's shilling*

This is probably just me since they're not particularly similar, but at one point Mason kept reminding me of a shit version of 90's Jamiroquai.

Che's voice can sound identical to Sam Smith at times but I prefer Ches voice he has a richer, more soulful tone than Sam does, his runs are up there with Brandy's!

I get a Joss Stone vibe from Louisa, only with more of a popstar edge!

Mason is reminds me of a less talented version of Chris Brown and a more talented version of Justin Bieber

Kiera's performance last night was something I could see Rita doing, from the song the dancers, the staging, even the outfit I could imagine Rita wearing!

Che, you remind me of a young Phil Jupitus.

Sorry for the Louis Walsh style quote...


And last year, Ben Haenow is a young George Michael.

BIB: Don't see it myself, but agree with the Monica/Amy, & Che/Sam Smith comparisons. The rest - jury is out.

Kiera - Solange Knowles
Monica - Adele
Lauren - Jessie Ware
Louisa - Christina Aguilera circa 1999

4th Impact - Destiny's Child
Alien - Pussycat Dolls

Seann - Rihanna / Freddie Mercury
Che - Sam Smith
Mason - Justin Timberlake / Robin Thicke
