Things are reportedly over for Katy Perry
and John Mayer
The music-powerhouse couple
have split up, with Perry, 29, breaking off the relationship, according to E! News.
"She was talking about him like everything was normal about two weeks back," a source close to Perry tells PEOPLE, adding that the couple "seemed pretty happy just a couple of weeks ago."
Over the last few weeks, Perry stepped out wearing rings on her left ring finger
, sparking a new round of engagement rumors. And, as recently as Valentine's Day, she and Mayer, 36, were spotted getting cozy during a night out on the town
in Los Angeles.
Mayer, however, was noticeably absent when Perry visited London and Milan this week.
Perry, who is gearing up for a world tour, reportedly returned back home to Los Angeles on Friday. Reps for both singers did not comment.
The on-and-off couple first began dating
in the summer of 2012, eventually weathering ups and down that saw them split up twice
. In recent months, however, the two appeared happy
, fueling rumors that an engagement might be imminent.
"[John]'s just a fantastic partner," Perry, who divorced Russell Brand
in 2012, said in a January cover story for Marie Claire
. "I've been a fan of his for such a long time. He's got a brilliant, brilliant mind. It's a rad, mature relationship."
The pair recorded a duet
, "Who You Love," for Mayer's latest album, Paradise Valley
, and they even shot a music video for it that showed them cuddling up and riding a mechanical bull.
"Relationships are kind of like riding a bull – you hold on for dear life," Perry said while promoting the video
on Good Morning America
. "Sometimes you get a little buck here and there, but you get back on."
