'The grand finale': Kourtney Kardashian shows off slim figure in black lingerie as she poses suggestively with legs open for daring selfie

She has been going wild lately on social media by posting photos where she is drinking wine, showing off her naked bottom and rejecting ex Scott Disick all over again.

But on Tuesday Kourtney Kardashian went the extra mile to pick up new followers when she posted a very suggestive selfie to Instagram.

In the snap, the 36-year-old mother-of-three has her legs spread open as she sits on a chair in her closet while modeling nothing but a skimpy black bra and panties.

A phase: The E! princess has her hair down and her expression looks dazed like an extra from Valley Of The Dolls. On the photo is written: 'The grand finale.' Her caption has a photo of a ghost

This comes just after Disick and the beauty posted a series of Snapchats while waiting around in a studio.

Introduced by his former partner as 'baby daddy Disick', Scott took a mock serious tone as he joked the couple were getting back together.

'Hey so we wanted to let you guys know first,' he said, addressing the camera as Kourtney filmed. 'We are getting back together.'

'We are getting back together!' Scott Disick jokes with ex Kardashian in a new Snapchat video on Monday... but she turns him down with a definite 'no!'

Still on good terms: The joking pair laughed together as they filmed for the app

But it was clear that Kourtney wasn't in agreement.

She squealed a definite 'no', although from the laughter in her voice, it's clear she still finds Scott funny.

Another video posted by Kourtney's little sister Kylie Jenner saw the 18-year-old ask in a questioning tone: 'So I heard on Snapchat that you guys are back together.'

After Kourtney laughed this off, Scott replied: 'She's just playing hard to get!' 

Jokes aside, the former couple still regularly hang out together - even without their children.

Scott joined Kourtney at a birthday meal to celebrate her brother Rob's 29th last week.

And he made his feelings clear when he told UsWeekly a few days ago: 'She’ll always be family to me and probably the person I love the most in the world.

'So even though we’re not together, we’re still close and it’s still nice to be around each other.'

The 32-year-old's confession came after he had spent part of the day with his ex and children Mason, six, Penelope, three, and 15-month-old Reign at Universal Studios’ Wizarding World of Harry Potter.

Always family: The former couple spend the day with their children earlier this month 

Scott remains on good terms with all of the Kardashian-Jenner clan despite his and Kourtney's break-up back in July.

Their decision not to exclude him is understandable - Scott had been part of their lives for 10 years during his on-off relationship with Kourtney.

The couple had appeared to be getting so close that last week Kourtney felt compelled to tell her fans that they weren't getting back together - something she revealed in another Snapchat video.

'By the way, everyone relax,' she told the camera. 'We have three kids together. We spend time together.'

In fact they are both moving on with their lives.

Scott has been seen with 20-year-old model Christine Burke, who bears more than a passing resemblance to Kourtney's half-sister Kendall Jenner, who is also 20.

And rumour has it that Kourtney had a fling with 22-year-old Justin Bieber in December.
