Scott Disick and girlfriend Sofia Richie's relationship is still going strong.

On Sunday, the couple, who started dating back in the summer of 2017, was recently spotted cuddling up together on a yacht in Miami, Florida. In Daily Mail's photos of the couple's outing, Richie, 20, showed off her gorgeous tan and toned figure in a bright pink bikini top and white linen pants. She paired the outfit with several silver necklaces, hoop earrings and dark sunglasses. The model kept her hair away from her face in a high ponytail.

Disick, meanwhile, looked comfortable in a light blue crew neck t-shirt and dark blue swimming trunks. The 35-year-old "Keeping Up With the Kardashians" star appeared to be in a good mood as he chatted with friends on the luxury SS Groot yacht owned by nightclub mogul Dave Grutman.

After their trip on the yacht, Disick and Richie were seen getting a ride in a Rolls Royce. The young model put on a black shirt over her bikini top and had a black leather bag slung over one shoulder as she sat on the passenger's seat of the luxury car.

Disick and Richie kept their romance low-key for months before finally making their relationship Instagram-official in September 2017.

The couple has since been enjoying getaways to several countries all over the world. Disick even once took his girlfriend during a vacation with ex Kourtney Kardashian, with whom he shares three kids: son Mason, 9, daughter Penelope, 6, and son Reign, 4.

Meanwhile, Kardashian seems to only be focusing on herself, her career and her kids these days. The mom-of-three recently shared a set of photos of her daughter Penelope after the child's first haircut.

“First ever hair cut in all of her enchanting six years,” the 39-year-old reality star captioned the snaps.

Andrew Fitzsimons, the celebrity hairstylist who gave Penelope her first haircut, also shared the moment on his Instagram Story. He posted a snap of the little girl's hair, along with the message, “Gave Penelope her first ever haircut today! That was pretty special.”

Aside from photos of her babies, Kardashian has also filled her Instagram with snaps showing off her gorgeous physique. In a post over the weekend, the older sister of Kim and Khloe Kardashian flaunted her bikini bod in a sexy one-piece swimsuit.
