Laila Hasanovic is a knockout—Jannik Sinner’s girlfriend has everyone in awe

After piquing her followers’ curiosity with a request for help putting together her costume, Laila Hasanovic has finally revealed her Halloween look. The Danish model, who is engaged to Jannik Sinner, chose to transform herself into a vampire for the night of October 31, sharing a few photos on Instagram that show her costume in detail.

“Anybody home? (followed by a red drop of blood, ed.)”, or “Is anyone home?”: this is the tongue-in-cheek question the 25-year-old chose as the caption for the post in which she revealed the final result, playing right into the spine-chilling atmosphere of Halloween night.

For the occasion, Hasanovic opted for a meticulously put-together outfit: a form-fitting, low-cut black dress with long, sheer sleeves embellished with floral lace details. Rounding out the look were straight brown hair parted in the center and, above all, particularly dramatic makeup. Her eyes were accentuated with dark eyeshadow and black eyeliner, while her lips stood out with a deep red lipstick. There’s also fake blood at the corners of her mouth, along with a striking silver necklace featuring a red stone, a dark ring, and burgundy nail polish.

The preparations had begun several days earlier. On October 25, Hasanovic had in fact posted a story on Instagram asking her followers for help finding a hairstylist and makeup artist in Los Angeles in preparation for the party. “I’m looking for a hair and makeup artist in Los Angeles for Halloween,” she wrote, without revealing what the final result would be. Curiosity was satisfied with the release of the photos, which showed the model dressed as a vampire.

It has been a particularly busy period for Sinner’s girlfriend, who has continued to make a name for herself in the fashion world throughout 2026. In August, she walked the runway at Copenhagen Fashion Week for OpéraSport, while in September she also took center stage at Milan Fashion Week, participating in the Genny show. In addition to her modeling career, Hasanovic is the founder of NRD55, a brand specializing in tanning products.

Meanwhile, her relationship with Jannik Sinner continues; it became public in October 2025, when the South Tyrolean champion thanked her during his victory speech at the Vienna tournament. Since then, Laila has often been seen in the stands supporting her boyfriend at major events on the circuit, though the couple has maintained a certain degree of privacy regarding their personal lives.
