Kim Kardashian is gearing up for her hosting debut on Saturday as she takes to the Saturday Night Live stage.

But, despite the show going out to millions, it appears as though the 40-year-old thinks she'll be the hostess with the mostess.

In the teaser video for the show, the reality star says: "Hi, I'm Kim Kardashian West and I'm hosting SNL with musical guest Halsey."

In the joke clip, cast member Cecily Strong jokes that the trio should form a brand new girlband - a suggestion that was quickly shot down by Halsey.

Kim goes on to tell Cecily she already had been shut down when asking about the idea backstage. "Ok, you could hear me," Cecily says. "I wasn't sure 'cause security had me in a headlock."

The SKIMS founder is later asked whether she is nervous about her new duties.

"Why? I don't have to write sketches do I?" Kim asks.

She's told no and is told she doesn't even have to memorise lines because she will have cue cards.

Kim then asks: "Everyone else won't look as good as me will they?," with Cecil replying: "No, absolutely not."

Kim replies with a smile, "This is so easy."

The skit comes after claims that Kim's estranged husband Kanye West had been helping her prep for the show.

Although Kim filed for divorce in February, the pair have regularly been seen supporting each other, including Kim dressing up as a bride during one of the 44-year-old rapper's album listening parties.

A source told Page Six : "Kim is nervous about hosting SNL. It's a big challenge but she is determined to be a success.

"Kanye is quietly advising her on her performance, her opening monologue, even her costumes for the show."

Rehearsals for the show started on Wednesday and Kim kept her fans up to date with events on Instagram.

After posting pics of herself getting ready to rehearse, fans flocked to the comments section to wish her luck. Among the well wishers was her mum Kris Jenner who wrote: "So excited!!!!"

Celebrity stylist Chris Appleton also commented: "Pretty! Your [sic] gonna kill it Saturday! I’m so excited for you, people are not ready."

As well as posting to her 257 million followers, the star took over the official Saturday Night Live Instagram account and shared stunning shots of her in a bright pink suit.

She followed up up with several different blingy outfits as she got her makeup done and posed for the cameras.
