Kim Kardashian was supposed to get a surprise 42nd birthday trip to Las Vegas, but she never made it to Sin City due to some unexpected turbulence.

This week’s new episode – entitled The Tension Is Brewing – happened just before Kim’s 42nd birthday, with her sister Khloe Kardashian and friend Tracy Romulus planning a surprise getaway to Sin City, to see Usher perform in concert.

While Kim admitted in confession that she ultimately knew about the trip to Vegas, she didn’t know about the Usher concert, though it was all for naught.

Kim was joined by Steph Shepherd, Malika Haqq, Tracy Romulus, Olivia Pierson, Natalie Halcro, Kris Jenner and Khloe on the trip that got cut short.

‘Today is the big surprise. So the plan is Kimberly knows we’re going somewhere and we’re essentially gonna kidnap her. We’re putting her in a party van with no windows that can see outside,’ Khloe says in confession before the trip.

Kim tells Steph Shepherd that she has no idea what they’re going to do and she thought, ‘I’d be spending my birthday in bed with the kids. I was like so chill.’

Kim adds in confession, ‘Today is my surprise birthday party. I’m playing along because Khloe is the best and like I know she’s worked so hard on this and I like don’t want to break her heart.’

Kim and Steph walk out to the van, as Kim admits in confession that she doesn’t know where in Vegas they’re actually going.

‘I know we’re going to Vegas but I don’t know why. I’m just gonna like hold on to that element of surprise,’ Kim says.

She arrives at the van and they all cheer, as the van takes off, as Khloe asks if she’s ready to go to a strip club.

‘Oh no, that is so not my vibe. Is that what we’re doing?’ Kim says as Steph jokes, ‘Why do you think you’re in a bra top?’

The van pulls into an airport hangar where showgirls are waiting, as Khloe adds in confession, ‘Like, we have showgirls, we’re going on a plane, obviously it’s nighttime already, so it can’t be a location that’s far. We’re not going to like Bermuda or something, she has no bags packed.’

Back in the hangar, they ask Kim if she can guess where she’s going, when she ultimately guesses Vegas.

‘We’re playing Usher music on the airplane… come on, Kim, help me help you. You really don’t know where we’re going yet?’ Kim says in confession.

Kim learns on the plane that they’re going to an Usher concert, adding in confession, ‘Oh my God, Usher in Vegas? I’ve heard the show is amazing. Now I’m so excited to be going to Vegas for my birthday with all my friends? A concert? It changes everything.’

They start taking Jello shots on the plane, adding in confession, ‘I’m such an Usher fan. Who isn’t an Usher fan, right? Like, he’s the best.’

Back on the plane, they start experiencing some turbulence, though Khloe says, ‘It’s known there is going to be turbulence, this is not a shock.’

They instruct everyone to put seat belts on, as Kris says in confession, ‘Well, I used to be a flight attendant, so I’m really good at being calm on a plane when there’s turbulence, but it seems a little extreme tonight.’

The turbulence continues as Kim says, ‘I have to make it to 43 please,’ as Khloe adds in confession, ‘I’m getting a little nervous, I don’t love turbulence. This isn’t the way the party is supposed to start.’

They notice that they are not landing like planned, as someone says, ‘We were about to, then we picked right back up.’

Khloe says in confession, ‘This is some scary s**t,’ while back on the plane, Khloe asks her mother what is happening.

‘Nothing, we’re just gonna try again,’ adding it was, ‘too windy’ so they are going to try landing again and if they can’t land this time they have to go back home.

Kim adds in confession, ‘We go down and then we pull back up, twice, and that scared me. The first time I’m like, oh you’re joking. And once I realized it’s not a joke, we actually can’t land, I’m like, I’m not messing with my life, like, let’s go home. But it sucks.’

The pilot reveals over the loudspeaker that the air traffic controller will not let them land in Las Vegas, ‘so unfortunately our only option now is to go back.’

Khloe adds in confession, ‘We feel so terrible for everyone who has moved mountains to make this experience so wonderful for Kimberly on her birthday. You make plans and God laughs.’

The plane lands safely back in Los Angeles as the pilot says, ‘Sorry it didn’t work out,’ as Khloe says, ‘No, thank you for making us safe.’
