Scott Disick, 37, and Amelia Gray Hamlin, 19, prove their relationship is going strong in Miami

Scott Disick and Amelia Gray Hamlin are still going strong in their relationship, despite their 18-year age-gap. 

The 19-year-old daughter of Lisa Rinna and Harry Hamlin looked stunning in a tiny white mini-skirt and bikini top as she strutted alongside her much-older man in Miami over the weekend, also spending time with her sister Delilah Belle Hamlin, 22.

Meanwhile, Keeping Up with the Kardashians star Scott, 37, kept his newly-bleached blonde buzz cut covered up in a black bucket hat before all three of them dipped in the pool of a nearby hotel. 

Still going strong! Amelia Gray Hamlin, 19, and her much-older boyfriend Scott Disick, 37, were pictured in Miami over the weekend, proving that their relationship appears to be going from strength to strength 

The pair could not keep their hands off one another as they cooled off at a hotel pool nearby after taking a romantic stroll on the beach.

Amelia was seen helping her boyfriend – who is 18 years her senior – get himself into the pool by holding out her hand for support.

Once the pair were in, Amelia was pictured doting on Scott and putting her arms around him in full view of the hotel guests.

The sighting comes amid much chatter about Scott’s past relationship with the mother of his children, Kourtney Kardashian.

Although Kourtney, 41, has moved on with former Blink-182 drummer Travis Barker, her situation with Scott is often called into question on their reality show. 

Kourtney and Travis, 45, who has two teenage children Alabama, 15, and Landon, 17, also spent this Easter together over the weekend.

However, in a most recent episode of KUWTK, Kourtney and ex Scott ended up in bed together talking about their lives.

Sister Khloe, who has admitted to rooting for the former couple, tried to explain the situation saying: ‘Kourtney and Scott are both getting here tonight thinking they’re meeting Kim and I for a family dinner. But we want to set up a Swiss-themed romantic dinner because we know that’s something Kourtney claims to love.’

She added: ‘Once the sun is setting, everything’s going to look more romantic and enticing and she will be overwhelmed by love.’

Scott – who said it was ‘pretty obvious they tried to set us up’ – also spoke directly to camera in a confessional about Kourtney and her family.

‘I think the family puts a lot of pressure on Kourtney more so than me in regards to them wanting her to be back together with me.’

‘They just see two people that spend a lot of time together, do a lot of things with their children, so why can’t we have a perfect family and a white picket fence? But it’s just not that simple.’

He concluded: ‘But to have a moment to just be together and see if we like being together without the kids, you know it was a cool thing.’

Despite all this, a source told People Magazine earlier this month that things are going well between Scott and Amelia.

‘He’s been telling friends how much she means to him and how into her he is,’ a source told the publication.

Meanwhile the source added that the pair are not worried about their 18-year-age-gap. 

‘She grew up in the industry and knows how all this works,’ the source explained. ‘It’s a different type of maturity, and they really don’t feel the age difference.’
