Tinie Tempah admits he didn't watch any episodes of 'The Voice' before appearing on the programme.
The 'Pass Out' rapper, who will help Sir Tom Jones coach his 12 chosen acts on the BBC show tomorrow night (01.03.14), didn't even known who was on the judging panel and was surprised to get the call.
He told The Sun newspaper: "To be honest with you, I hadn't really met Tom before.
"My manager called me and said, 'They want you to do it. Are you up for it?' and I said yes.
"He was on before me at V Festival one time and I met him before that and introduced myself to him, but not really so it was a lovely experience to hang with him."
Asked if he thinks he has more in common with the other judges, he struggled to name the new line-up after The Script's Danny O'Donoghue and Jessie J left last year.
He said: "Danny's not doing it any more? It's the Kaiser Chiefs? And Kylie now?
"So it's whatshisname, Tom from the Kaiser Chiefs? The other Tom ... Tom Jones, and who is the other one? will.i.am? Oh, sorry Ricky? My bad."
But Tinie, 25, eventually praised the judges - Kylie Minogue, will.i.am, Ricky Wilson, and 73-year-old Tom - who he says is still "alive and kicking".
He said: "He looks amazing, he's up for it, he's charismatic, very funny, a pleasure to be around.
"will.i.am is cool! I like the way he delivers his criticism, he's not really an a***hole about it. And I like the way he dresses so well. It's like he's come from the future.
Tinie added: "I'll watch The Voice from this weekend and from then on."

'Call the Midwife' and 'Death in Paradise' have been commissioned for new series.
Both hit BBC shows will return for a fourth series, BBC's controller of drama commissioning Ben Stephenson and BBC One controller Charlotte Moore have confirmed.
Period drama 'Call the Midwife', which stars Jessica Raine as midwife Jenny Lee, has been a consistent draw on Sunday nights, with more than eight million viewers tuning in each week.
Meanwhile, 'Death in Paradise' has continued to enjoy strong ratings despite losing lead actor Ben Miller, who has been replaced in the new series by Kris Marshall.
In addition to the renewals, BBC One has commissioned several dramas including a new adaptation of 'Poldark'.
'Being Human' star Aidan Turner has been cast in the lead role of Ross Poldark, who returns to his beloved Cornwall in 1783 after fighting in the American War of Independence, only to discover nothing is the same as he left it.
Aidan said: "I'm very excited to play Ross Poldark for the BBC and it's obviously a huge challenge to honour the extraordinary character Winston Graham created and who Debbie Horsfield has brought new life to."
Meanwhile, BAFTA-winning actress Sheridan Smith will star in one-off cancer drama 'The C Word', which is based on the real-life experiences of Lisa Lynch, who was diagnosed with breast cancer shortly after getting married and turning 28.
The 90-minute drama will begin filming in May.

David Walliams is set to star in a new crime series on BBC One.
The comedic star will take a lead role as one half of married detective duo Tommy and Tuppence in 'Partners in Crime', a six-part series based on novelist Agatha Christie's two books, 'The Secret Adversary' and 'N or M'.
David - who also co-wrote the series - said: "In bringing these thrilling stories to the screen, it is our ambition for Tommy and Tuppence to finally take their rightful place alongside Poirot and Marple as iconic Agatha Christie characters."
The programme is the first in a string of novels which will be adapted for television in a bid by the BBC to celebrate what would have been the author's 125th birthday.
The famous crime writer - who died in 1976 - will also have her life explored in a series of documentaries to mark the occasion.
Next year, BBC will air a three-part adaptation of 'And Then There Were None', written by playwright Sarah Phelps.
Much of Christie's famous works have been adapted by ITV over the past 20 years, with the broadcaster recently ending its long-running 'Poirot' series starring David Suchet as the iconic Belgian detective.

'Coronation Street' will not be investigated by Ofcom over a gay kiss scene.
The ITV soap featured a raunchy half-naked embrace between Todd Grimshaw (Bruno Langley) and Marcus Dent (Charlie Condou) last week, which resulted in around 100 viewers to complain to Ofcom because the "sexually suggestive" footage aired before 8pm when many children were watching.
However, the broadcasting regulator refuses to act on the complaints since they don't want to "discriminate" between homosexual and heterosexual relations on screen.
A spokesperson for Ofcom told MailOnline: "Ofcom can confirm that it is not investigating the scene in 'Coronation Street' as it was not in breach of generally accepted standards. Our rules do not discriminate between scenes involving opposite sex and same sex couples."
Ofcom was forced to assess whether any broadcasting guidelines had been broken but it seems the "majority" of viewers didn't have a problem with the footage since it simulates a real life situation.
An insider told the Daily Star newspaper: "The vast majority of the audience have no trouble with this. It's real."
This isn't the first time Todd has caused controversy on the show, emerging as Weatherfield's first gay character and initially leaving the street in 2005 after he came out to then girlfriend Sarah Platt (Tina O'Brien).

Kanye West is reportedly jealous of Pharrell Williams.
The 'Blood On The Leaves' rapper is said to be keeping a close eye on the 'Happy' hitmaker after reports he is close to signing a deal with Adidas, the same sportswear brand that Kanye has been commissioned to design a clothing range for.
According to The Sun newspaper, a source revealed: "They are competitive in both music and fashion, Kanye always watches what Pharrell does. He thinks having a similar artist working on their own brand for Adidas will make his collection less special."
Kanye signed a deal with Adidas in December last year after a spat with the Nike - over royalties for his exclusive collection of Air Yeezy sneakers - which resulted in the end of his business relationship with the sportswear brand.
Meanwhile, the 36-year-old rapper has announced plans for his very own movie, which follows his 'Yeezus' tour.
A release date for the film is still to be confirmed, and it is believed his fiancée Kim Kardashian - whom he shares eight-month-old daughter North with - is set to play a "pivotal" role.

Kanye West has announced a movie based on his 'Yeezus' world tour.
The 36-year-old rapper has teased the concert film, which will be directed by frequent collaborator Hype Williams, with a 30-second teaser trailer on his official website.
The trailer intersperses footage from his ongoing world tour, as well as clips from his recent 'Bound 2' music video which featured his fiancée Kim Kardashian.
The website states: "Yeezus film directed by Hype Williams coming to theatres".
Music video director Hype Williams has previously been entrusted to helm the elaborate visuals for Kanye's hit songs 'All of the Lights', 'Stronger' and 'Gold Digger'.
The 'New Slaves' star has recently been linked to a biographical film based on his 'Yeezus' album and it's rumoured Kim, 33, may have a starring role.
Author Bret Easton Ellis divulged details of the secretive project, revealing he has been approached to pen the script but was initially reluctant to sign on.
He said: "I didn't want to at first. Then I listened to 'Yeezus' and I thought, regardless of whether I'm right for this project, I want to work with whoever made this."
Kanye isn't expected to star in the film, but Kim - who is the mother of his eight-month-old daughter North - is being lined up for a "pivotal role".

Jack Nicholson celebrated what would have been Elizabeth Taylor's 82nd birthday on Wednesday night (26.02.14).
The 76-year-old actor was among the celebrities at the glamorous gathering held at the Cassandra's Violet Grey store in Melrose Place in Beverly Hills, which was hosted by Paramount boss Brad Grey's wife Cassandra, to celebrate the legendary actress.
The Hollywood icon - renowned for his prowess with the ladies - was in his element at the bash as he was nestled between model Erin Wasson and the granddaughter of artist Picasso, Diana Widmaier-Picasso, while locking eyes with Eva Mendes across the table.
According to the New York Post newspaper's Page Six column, Jack appeared to be enjoying himself at the intimate bash as he exchanged life stories with guests, before bursting out in laughter.
Pharrell Williams, Chanel Iman, Anjelica Huston, Carole Radziwill and Alice Eve also paid their respects by attending the birthday bash for the screen star, who died of congestive heart failure in 2011, aged 79, after suffering many years of ill health.
Meanwhile, other stars took to their Twitter accounts to mark the special day.
Kim Kardashian wrote: "Happy Birthday to the legendary Elizabeth Taylor! Forever grateful for your last interview we did together! I will never forget it! #MyInspiration #MyIdol (sic)".

Selena Gomez has won a Young Humanitarian Award.
The 21-year-old singer was awarded the accolade at the unite4:good and Variety's unite4:humanity gala, held at the Sony Lot in Los Angeles, California, last night (27.02.14).
The 'Spring Breakers' star was honoured after being recognised for promoting positivity, inspiring charitable engagement and empowering acts of kindness towards the children's charity UNICEF.

Ashley Roberts got "emotional" at Kimberly Wyatt's wedding.
The blonde star acted as the Maid of Honour at her Pussycat Dolls bandmate's nuptials to Max Rogers on February 22 and Ashley couldn't hold back the tears when they began to walk down the aisle.
Talking on British chat show 'Lorraine', she said: "Kimberly was the first one out of all of us. Kim and I were friends even before we were in the Dolls, and so she's my sister. I got emotional as the Maid of Honour. I took one step down that aisle and I just ... Max said to me, 'Don't do, it don't it.' And I was like, 'Wah!' It was a beautiful, beautiful day."
Following the ceremony Ashley, 32, wished the newlyweds well and hopes they have a fairy tale ending.
She wrote on Twitter: "Congrats to the newly married couple @max_rogers @KimberlyKWyatt !! Was truly a fairy tale day. Here's to happily ever after (sic)"

Kristin Davis says 'Sex and the City 3' will be down to fan support.
The 49-year-old beauty stars as Charlotte York alongside Sarah Jessica Parker, Kim Cattrall and Cynthia Nixon in the film spin-offs based on the popular TV series of the same name, and admits their huge fan base was the reason they considered the big screen productions in the first place.
Talking on British programme 'The Jonathan Ross Show' she said: "If the fans weren't interested I don't think it would ever happen.
"It was a struggle to get both the first movie and the second movie made, partly because we're a franchise starring four women over 40 and that just frankly doesn't happen.
"It's only from our fan support that anything ever happened ever in the film region. I think the third if it does happen is because people talk about us, we're still on the air, there is the fan support and so it means a lot to us."
Earlier this month director Michael Patrick King admitted 'Sex and the City' has another story left to tell but remained cryptic about whether he would helm a sequel to 2010's film.
He said: "Sarah Jessica and I both know what that final chapter is. That doesn't mean it will or should be told, but I do think there's one story left. Whether it ever happens is a whole other situation. But there's four girls, and those girls are still in my mind. There are other stories to tell and characters that haven't even been written yet."
This comes after Parker revealed she isn't ready to throw away her Manolo Blahniks and would happily reprise her role as style icon Carrie Bradshaw, as long as the sequel happened in the near future.
She confessed: "A part of me thinks there is one last chapter to tell. But timing is a peculiar thing. It isn't a decision that can wait forever. I don't want to have to wear muumuus [a loose dress that hangs from the shoulders]!"

'12 Years a Slave' has been added to the school curriculum in the United States.
The National School Boards Association (NSBA) have joined forces with talk show host Montel Williams to make it mandatory for public high schools to teach students the story behind the Oscar-nominated film, which is based on the memoir of Solomon Northup who was abducted and sold into slavery.
Williams said: "When Hollywood is at its best, the power of the movies can be harnessed into a powerful educational tool.
"This film uniquely highlights a shameful period in American history, and in doing so will evoke in students a desire to not repeat the evils of the past while inspiring them to dream big of a better and brighter future."
NSBA and Williams have partnered with New Regency, Penguin Books and the filmmakers to distribute copies of the film, book and study guide to schools across the country.
The Steve McQueen-directed film has been nominated for nine Academy Awards including Best Picture and Best Actor for Chiwetel Ejiofor's outstanding performance as Northup at the ceremony taking place this on March 2, 2014.
