The "Espresso" singer and the Saltburn star called it quits late last year, but the post-breakup timeline keeps getting messier.
This week, Keoghan was photographed leaving a Los Angeles gym wearing what eagle-eyed fans swear is the same vintage Cartier ring Carpenter gifted him during their whirlwind romance.
Neither camp has commented, which, in Hollywood, is basically a press release.
The pair met on the set of a music video, went Instagram-official with matching chaos, and became the internet's favorite odd-couple pairing by early 2024.
By December, sources were whispering about conflicting schedules.
By January, the whispers had turned into a full tabloid chorus.
The ring sighting is the first real breadcrumb since.
Carpenter's team has been conspicuously quiet about her dating life while she rides the Short n' Sweet tour into a Grammy-season victory lap.
Keoghan, meanwhile, has been spotted at the same Hollywood haunts as a certain A-list actress whose name keeps getting scrubbed from DeuxMoi submissions.
Fashion detectives on TikTok have already zoomed in on the jewelry, comparing it to a piece from a 2023 red carpet look.
The ring, if it is the ring, would be a strange choice for a man who reportedly moved out of their shared rental months ago.
Then again, Hollywood men have worn more confusing accessories to the gym.
What's really fueling the gossip is the silence.
No joint statement, no cryptic Instagram story, no "we remain friends" PR boilerplate.
Just two people living their lives in the same zip code while the internet plays detective with their jewelry box.
It's the kind of low-grade mystery that keeps breakup rumors alive for months longer than they should be.
Meanwhile, Carpenter's tour wardrobe has gotten noticeably sharper, and her onstage banter has gotten noticeably sharper too.
If there's a song about a man who couldn't return a ring on the next album, nobody would be surprised.
Our take: this is a classic Hollywood slow burn, the kind that drags across award season and resurfaces every time one of them books a new project.
Final Thoughts
Either way, we'll be watching the next red carpet like it's a crime scene.
