Scott Disick, 37, and his girlfriend Amelia Gray Hamlin, 19, take their kids to dinner in Miami

Things seem to be getting serious between Scott Disick and his girlfriend Amelia Gray Hamlin.

On Saturday night, the 37-year-old vet and 19-year-old girlfriend were seen taking their three children Mason, 11, Penelope, eight, and Reign, six, for a sweet treat at the Sugar Factory in Miami.

The couple continues their romantic South Beach vacation adventures – now with him bringing their children – as they continue to grow strongly since they left in October.

Scott continued to debut his new pink cotton candy strands while wearing cargo pants and a gray hoodie.

He was seen hand in hand with Penelope and Reign – both novice fashionistas – as they headed for the South Beach location.

Amelia wore black jeans and a pair of Bottega Veneta heels, opting for a sexy one-shoulder top for the family gathering night.

Only eight years older than Mason, she seemed to be settling in the family very well while making her way behind the litter with a friend.

Upon arriving inside, Disick was seen holding a steaming bowl of something sweet surrounded by candy – certainly any child’s dream – despite the fact that mother Kourtney Kardashian is notoriously rigid about her children’s diet.

Last week, Disick took Amelia for a Valentine’s Day in Miami, and it looks like he gave her the new gold Rolex on her wrist as a romantic gesture.

Disick posted with the teenager on Instagram just before the holiday, when they made their romance official for the first time.

The two were seen having dinner at the sophisticated Carbone restaurant as he put his hand around her chair while smiling from ear to ear.

Before, they had gone for a ride in their showy green Lamborghini before spending the afternoon on a boat in Biscayne Bay.

That same week, they were seen packing on the PDA on the beach while taking a walk in the ocean hand in hand, with a source saying that they ‘looked very much in love’.

On Friday, he continued to mix Amelia with his circle, when they were seen having lunch with Kardashian’s confidant, Jonathan Cheban, and the surprising guest, Larsa Pippen, the now unhappy family friend.

The sighting came on the same day that Kim Kardashian announced her divorce from Kanye West after seven years of marriage, when Amelia was seen sitting next to the ex-Miami housewife talking.

Not on their first trip together, the couple spent the New Year in Mexico and also went to the interior of the state of Santa Barbara, as he also approached his sister Delilah’s boyfriend, Love Island, Eyal Booker.

Perhaps a routine when it comes to their age difference relationships, Disick was photographed at the Sugar Factory years ago with his ex-girlfriend, Sofia Richie, before breaking up in the summer.

Although Sofia was hurt that he left with someone she once considered a friend – causing her to stop following the Hamlin sisters – it was said that she was not ready to be a ‘stepmother’ to his children and that the relationship was getting very serious.

Now the lady in charge appears to be Amelia, but it has been said that the pair is taking too long.

– Scott and Amelia are having a great time. They are hanging out with friends, spending time together and, in general, just having fun, ”a source told ET.

‘They are still not very serious and are just taking things from day to day and keeping things light and fun’, adding that ‘Scott likes things to be discreet and easy with her [Amelia]. ‘
