Taylor Swift wears Travis Kelce’s birthstone while out on date in NYC

A not-so-invisible string.

Taylor Swift and Travis Kelce had a romantic date night in New York City on Friday, with the singer adding a sweet tribute to her beau by way of some special jewelry.

Swift wore a Foundrae opal necklace charm ($2,250) around her neck — with the gemstone serving as Kelce’s birthstone (no coincidence there).

“This Opal Gemstone Heart symbolizes Love. True Love binds the heart forever… The heart is love. When we open ours, we connect with others,” the bauble’s description reads.

She piled on more bling from the brand, adding a diamond chain necklace ($15,650) as well as another sentimental gem: An Anita Somayaji Sagittarius necklace ($2,700).

The symbol represents the “Cruel Summer” singer’s own zodiac sign, but the bow-and-arrow charm also has a connection to her NFL pro beau; the archer is coincidentally his signature touchdown pose.

Swift also rocked her $33,200 Panthère De Cartier watch to complete the high-price tag stack.

As for the rest of her date-night outfit, the musician opted for a Reformation corset top ($168) and a Miu Miu poplin miniskirt ($1,019) with white pumps and a cream Mansur Gavriel purse ($595).

Kelce, 35, for his part, wore a US Soccer x Nike knit polo ($105), white knee-length shorts and white sneakers.

This isn’t the first time that the Grammy winner has subtly shown her love for Kelce, whose birthday is October 5.

In September 2023 — before the couple publicly confirmed that they were together — she gave fans something to talk about when she wore a different Foundrae opal charm.

She wore the brand’s Forever & Always a Pair Pendant ($1,400), which also happens to share a name with one of her “Fearless” album hits.

On Friday night, the couple was spotted holding hands as they left Torrisi, one of their favorite restaurants in the Big Apple.

Swift and Kelce last hit up the celebrity hotspot in October, with the Grammy-winning singer in — surprise, surprise — a gold corset top and matching miniskirt.

Swift had been spending time in Florida with the Kansas City Chiefs player while he trained during the off-season. However, he has returned to Missouri for official camp with the team ahead of his thirteenth season in the league.
