Cody Simpson and fashion model girlfriend Gigi Hadid are inseparable more than ever. The lovely twosome spent some quality time together at a Miami beach over the weekend.

Hadid, 19, and her 18-year-old Australian pop singer boyfriend were not afraid to show their affection for each other since they were photographed smiling, laughing, kissing and hugging in the ocean, reports E! News.

Simpson, who rocked Hurley boardshorts, was even spotted lifting Hadid for a romantic kiss in the water.

Hadid, who wore a retro stripe bikini top and bottom, took to Twitter to express her love for the "La Da Dee" singer. "Hey @CodySimpson I❤U," she wrote.

After their weekend rendezvous, Yolanda Foster's daughter tweeted about her happiness to be getting some shut-eye in her own bed again.

"Nothing feels as good as being in your own bed again after a month goooooodnight sugaplums!" she captioned a photo of her lying on her bed.

However, the busy weekend for the young Hollywood couple didn't pass without controversy. Cody Simpson's Snapchat video of Hadid apparently created a huge buzz after several netizens and OceanUp pointed out that she was allegedly snorting cocaine in the clip, according to Us Weekly.

But Gigi denied the claim and even insisted that she has been nothing but a good role model.

"I take pride in being a good role model, would never touch that, & will not stand for or put up with a little piece of scum blog like OU," the Sports Illustrated model wrote on Twitter.

"If u actually watch the video there is nothing on the counter .5 sec's before you see that image...It's not only impossible but insane to me," she further clarified.

"Besides for doing the supposed in general, I'd be an idiot to do that at a WORK EVENT in front of hundreds of people/press. I'm insulted," she added.

Born Jelena Noura Hadid, the blonde beauty is the daughter of Foster and Grammy-winning singer-songwriter David Foster.

Daily Mail says Hadid is becoming one of the biggest names in the modeling world after landing contracts with Guess and Maybelline.
