Is Karlie Kloss Cheating On Boyfriend Joshua Kushner? Trouble In Paradise After Years Together?

Karlie Kloss and her billionaire boyfriend, Joshua Kushner, have been together for years, but have they outgrown each other already?

The Victoria's Secret angel has reportedly getting cozy with Vanity Fair's Man On The Street Derek Blasberg recently, and the Instagram co-founder has allegedly been left out from his girl's vacations and trips.

Kloss and Blasberg supposedly grew close after working together on Kate Spade's holiday campaign.

Could their professional relationship have turned into something more personal in recent weeks?

"The holiday season is (almost) in full swing, and Kate Spade New York is kicking it off with its new festive campaign starring runway superstar Karlie Kloss, who appeared in the preppy brand's fall 2015 ad, and Vanity Fair's Derek Blasberg," Hollywood Reporter wrote in the article.

Karlie Kloss' boyfriend Joshua Kushner has been pointedly absent in the supermodel's social media updates. Despite posting photos of her campaigns and her squad with Taylor Swift, Cara Delevingne, Gigi Hadid, as well as her fellow Victoria's Secret models, photos with her boyfriend of several years.

However, she did upload a photo of herself on a yacht during a recent vacation in Saint-Jean, Saint Barthélemy. Kushner, on the other hand, seems to be nowhere in sight.

Further reports suggested that the 23-year-old fashion enthusiast might have hidden her vacation with the writer from her boyfriend. She also reportedly returned home to New York City alone, without her boyfriend to accompany her.

On the other hand, she's busy with her first semester at NYU. Being a full-time model and a student in a prestigious university might have been too hectic for the couple to see each other constantly.

Meanwhile, no formal statement has been released by the supermodel.

Could Karlie Kloss and her boyfriend Joshua Kushner just taking a break to focus on their own schedule or have they really broken up now?
