The presenter, who works with Olly on ‘The Voice’, admitted Olly is a “superfan” of the Channel 5 reality series and is desperate to be a housemate.
The only thing stopping him is his management, who have put a block on him appearing.

Olly Murs wants to do 'Celebrity Big Brother', according to Emma Willis

Speaking to HuffPost UK at the press launch of ‘The Voice’, Emma said: “Olly has watched it since the day it started. Every episode - he’s a bit of a superfan like me.
“I didn’t know this until about half an hour ago and he said ‘I want to go in it. I just want to go in it and my management won’t let me go in.’
“I said, ‘And I’m not surprised!’.”
Emma also predicted fellow ‘The Voice’ coach Sir Tom Jones would win the show over Olly, Jennifer Hudson and Will.i.am if they all entered the ‘CBB’ house.
She continued: “Tom was nearby and said, ‘What you talking about, it’s just a bunch of people in a house, isn’t it?’. Then someone said, ‘You should go in, Tom’.
“If he went in, he would just walk it in a heartbeat. Just an amazing man.”

Asked how Olly and Tom would fare will the current all-female line-up, which includes the likes of former Tory MP Ann Widdecombe and Boris Johnson’s sister Rachel, Emma added: “They are just two lovely boys. They’re both very smooth, and they both love women so they’d have a dream in there.”
Olly is a new addition to the ‘Voice’ coaching line-up this year, after jumping ship from ‘The X Factor’, where he originally found fame as a contestant in 2009, before going on to host the show in 2015.
And it seems he is proving to be a more natural coach than he was a presenter, with Emma telling us: “I think Olly brings a fantastic energy - he’s so excited and so into it, and he really wants to prove himself.
“He’s been quite cheeky on camera and on set, and a little bit flirty with a couple of the contestants, but he’s been fabulous.”
‘The Voice’ returns on Saturday (6 January) at 8pm on ITV.
'The Voice' UK: Where Are They Now?

It seemed the BBC may finally have found a star with Jermain. Regrettably, this wasn't the case, and his debut album peaked at number 42 in the charts after its 2015 release. (credit:Dave J Hogan via Getty Images)
Leanne Mitchell (Winner, 2012)(03 of14)

Sadly, the show's first ever winner found herself dropped in 2014, after releasing just one album.
Leanne later blamed the fact her label waited too long after her victory on 'The Voice' in releasing the album for its lack of commercial success, claiming she was still happy she didn't "cop out" and release a covers album. (credit:Mike Marsland via Getty Images)
Tyler James (Runner-up, 2012)(04 of14)

Tyler "I Was Best Friends With Amy Winehouse" James (she's mentioned six times on his Wikipedia page alone) was a fan favourite during the first series of 'The Voice', famously performing a duet with will.i.am dangling from the ceiling.
This didn't translate to a fruitful music career, though, and his last offering in 2012 stalled at number 47 in the UK album chart. (credit:REX/Brian Rasic)

Despite having the most commercial success of any of the former 'Voice' stars, Bo didn't have an easy time after leaving the competition, and quit her record label after two singles due to a "lack of support", before eventually checking into rehab for exhaustion.
She's since branded former coach DannyO'Donoghue a "wanker" after admitting that they shared a snog while she was still being mentored by him on the show. (credit:Rex/Jason Sheldon)

Vince has continued to make music since appearing on the show, releasing four singles, though none managed to chart in the UK. (credit:Rex)

She was already a successful musical theatre actress when she auditioned for 'The Voice', but none of the judges turned their chairs for Twinnie.
Since then, she's focussed on acting and in 2014, began playing a McQueen in 'Hollyoaks'. She also, judging from this photo, loves a good hat. (credit:Rex/Tom Horton)
While it seems he may not have been successful, Jamie is continuing to make music and keeps fans updated online. (credit:Rex/Beretta/Sims)

Leah's cover of 'I Will Always Love You' may have charted at number 8 while she was on the show, but her efforts after the competition couldn't match it.
Despite support from will.i.am - who invited her to support him on tour - Leah's debut album failed to materialise, and she was quietly dropped by her label. (credit:Neil Lupin via Getty Images)
Andrea Begley (Winner, 2013)(10 of14)

Andrea famously caused will.i.am to storm off set when she was announced as winner over his act, Leah McFall.
Andrea had huge success - by The Voice's standards... - in 2013, when her debut album charted a number 7.
We haven't heard much from her since then though, and after its release, she completed her Masters degree in Law and Governance... which would appear to suggest we won't be hearing a follow-up anytime soon. (credit:Harlem Mepham via Getty Images)

Former Liberty X star Kevin triumphed on what would be the last BBC series of 'The Voice'.
Unfortunately, he couldn't break the show's curse, and his solo album 'Recover', failed to chart when it was released in October 2016. (credit:Jeff Spicer via Getty Images)
