Alongside a snap featuring a selfie of them together, she wrote in the Instagram caption, "3rd valentines with you❤️."

Aside from being head-over-heels in love, the teen is also following in her mom's footsteps and focusing on her new career as a model.

During an appearance on the Today show in June, mom Heidi, 49, shared her excitement that Leni is embarking on her modeling dreams as she revealed her daughter will be moving to New York City.

"She's moving to the Big Apple. It's kind of my first stomping grounds, so I feel like she's doing it all over again. I'm so proud of her!" Heidi told Jenna Bush Hager and Willie Geist.

"She has been [modeling] for the last year, which is incredible. She walked for Dolce & Gabbana. She's actually, in a few weeks, doing the show again in Sicily," the mother-of-four proudly shared.

The Making the Cut host expressed that working is just half of Leni's impressive plans. "I'm so excited for her, but more excited for her that she just got into the school she always wanted to go to."
