Cheeky: Keeping Up With The Kardashians 20 seasons has shown the ups and the downs of Kourtney Kardashian and Scott Disick’s rocky romance. And during the latest teaser for the final season of the series, Kourtney, 41, and Scott, 37, enjoyed a flirty evening together – by accident

The teaser kicks off with Kourtney lounging in bed in her feathered pajamas, as she says ‘I’m staying at the Malibu house alone tonight. Its nice that i can really work and focus on Poosh.’ 

But she hears a sound and is heard saying: ‘Is someone here?’ She jumps out of bed and heads toward the front and says ‘Hello?’

 ‘Oh my gosh! What are you doing?’ she says to Scott, after finding him in the kitchen; he answers just with ‘oh.’

They ask each other why they are at the Malibu house.

Kourtney says she needed to work on some Poosh stuff and Scott says he ‘wanted to be by the water,’ adding that he ‘didn’t know’ she was going to be there that day.

‘Where are Mason and Reign?,’ Kourtney asks, to which Scott says ‘At mom’s,’ referring to Kris Jenner.

 Scott asks about their daughter, Penelope, and where she was.

‘She wanted to sleep at Khloe’s,’ Kourtney said.

‘Its like the world’s bringing us together,’ Scott notes. ‘Wanna watch a movie?’

‘Yeah we can,’ Kourtney answers.

‘Ever seen a man eat a Milky Way with a fork and knife?’ Scott asks her.

‘Nope,’ she says, before he adds ‘It’s very classy.’

 ‘Is it? she says with a smile during the flirty exchange. 

‘Oh yeah,’ Scott replies. ‘Shall we?’ as he leads the way to the living room. 

Speaking directly to the camera, Kourtney says: ‘I can’t remember the last time Scott and I spent time alone together without the kids. It’s been years since we did this and its just a little bit weird.’

Back to their evening together, they sat next to each other of the couch, as Kourtney nibbled on a cookie.

‘How’s that cookie, it looks insanely good,’ he asks her as she delicately munched on it.

‘It is,’ she says before she puts the entire cookie flat into her mouth.

‘Look at the way your placing that in your mouth. That was exquisite,’ as she laughs and chews up the large piece of cookie.

‘You’re an unbelievable woman,’ he declares, which Kourtney heartily agreed to and added, ‘I know.’

Changing the subject, Scott asks her what she is working on, as far as Poosh stuff.

Full of compliments: ‘Look at the way your placing that in your mouth. That was exquisite,’ as she laughs and chews up the large piece of cookie

‘I think I’m going to do an article right now on celibacy. I have to research it. I’m just getting started,’ she said.

‘Oh we practiced celibacy for a while,’ Scott adds.

‘No we still had sex even though you think we didn’t,’ she says.

‘You told Sarah Howard you thought I was a porn star when we first started hooking up,’ he reminds her.

‘I remember but I don’t sit there and dwell and think about…’ she starts, before he says ‘There’s no dwelling baby. You were the porn star one time.’

She giggles and looks away and says ‘definitely not’ but then gives him a flirty smile.

Work: ‘I think I’m going to do an article right now on celibacy. I have to research it. I’m just getting started,’ she said

‘I forgot how nice it is to just have a conversation with Scott without the kids. We’re friends,’ she says in an interview with Scott besides her.’

He adds: ‘Purely platonic,’ looking wistful and sad about it.

Kourtney giggles and Scott asks, ‘What’s so funny?’ to which she says ‘I don’t know.’

 Kourtney and Scott dated on/off from 2006 until they split for good in 2015.

They shared three children:  Mason, 11, Penelope, eight, and Reign, six.
