Katy Perry was spotted wearing a ruby ring on her wedding finger, sparking rumors she's engaged to musician John Mayer, E! News reported.
Perry's representative declined to comment on the star's relationship status.
In an appearance on CBS' "Sunday Morning," last weekend, Mayer said he thinks he'll eventually tie the knot one day.
"I mean, I'm still the kid from Connecticut. That's what you do," he said.
