Scott Disick still gets "turned on" by Kourtney Kardashian.

The 33-year-old TV personality split from the mother of his three children - Mason, seven, Penelope, four, and their two-year-old son Reign - in 2015, but Scott has admitted he's still attracted to the curvaceous star.

Scott's confession came during a conversation between himself and Kourtney's sister Khloe Kardashian, in which she grills Scott about whether he and Kourtney kissed during a family vacation in Mexico last year.

In a clip from an upcoming episode of 'Keeping Up with the Kardashians', Scott jokingly reveals Kourtney "didn't kiss me back when we were together".

But Khloe continues to probe, asking: "Did your sausage like move in your pants a little because it got excited?"

And Scott responds, candidly: "I'm still turned on by her, if that's what you're asking."

The reality TV star subsequently admits he still loves Kourtney, even if there is no immediate prospect of them reuniting their on/off romance.

He said: "I feel like I will never be over her. She's the love of my life, but I just try to do everything to be there for her, but there's literally no appreciation for anything ever."

Scott's party-loving lifestyle led to the collapse of his relationship with Kourtney and while he acknowledges he was largely to blame for their break-up, he is eager to see his family reunited.

He explained: "I definitely realize that a lot of things truly are my fault and I'm happy taking ownership for all that."

And Scott believes Kourtney still doesn't understand quite how much she means to him.

The TV star - who has previously admitted to drinking and partying excessively - said: "I just hope that one day she understands that I would never want to be with anybody but her."
