Katy Perry looked positively radiant at the MTV Europe Music Awards in Amsterdam on Sunday, Nov. 10. The singer arrived on the red carpet wearing a form-fitting and figure-flattering Zac Posen dress, which she paired with a Dolce & Gabbana headband and Charlotte Olympia heels. What really got people talking, however, was the diamond ring on the pop star's engagement finger.
The sparkler reignited rumors that Perry is engaged, though reps for both the "Unconditionally" singer and boyfriend John Mayer did immediately return request for comment when contacted by E! News.
Dating on and off for the last year, this would be the second marriage for Perry (who was briefly married to Russell Brand) and the first for Mayer (whose famous exes include Jessica Simpson, Jennifer Aniston and Jennifer Love Hewitt).
While it's unlikely that the rocker popped the question—this certainly isn't the first time Perry has worn bling on that finger—the musicians are heading in that direction.
"Everyone wants them to get engaged," a source recently told E! News. "They are so perfect together." The source added that a proposal is "inevitable," though not necessarily in the immediate future.
Perry, 29, and Mayer, 36, took their romance public in the summer of 2012. The two have also made music together, with the latter co-writing the bonus track "Spiritual" off Perry's album, Prism. The raven-haired singer also leant her vocals to "Who You Love," which appears on Mayer's Paradise Valley.
