Taylor Swift wears boyfriend Joe Alwyn's initials on a ring to 'Cats' wrap party

Taylor Swift meant it when she sang "I want to wear his initial."

The 29-year-old singer just finished up production on the Cats movie and posed for a selfie with her co-star, Eric Underwood, at the wrap party. Swift is playing Bombalurina in the movie while Underwood takes on the role of Admetus.

"And that’s all folks with @taylorswift #catsmovie #thewrapparty #lotsoflove #shesincrediblethatsall," Underwood captioned the pic.

Keeping to the feline theme, Swift wore leopard print to the party, but fans were more focused on one of her accessories. Several Swifties pointed out in the comments that the pop star was wearing a gold ring that had the initials J.A., the same initials as her boyfriend, Joe Alwyn. 

Needless to say, fans were freaking out over the ring. "Omg the 'JA' ring on her hand," reads one comment.

"HE HAS JOE'S INITIALS ON HER RING, OML I LOVE THEM," another fan wrote.

The couple have been dating for nearly two years, and while Cats was filming in London, Swift was able to support Alwyn by attending a BAFTAs after-party with him.
