Miley Cyrus and boyfriend Liam Hemsworth are constantly seen strolling down red carpets hand in hand, but could the two be ready for a trip down the aisle?
Cyrus, 19, sparked speculation over the weekend that she and "Hunger Games" star Hemsworth are getting hitched when they made the rounds at an event in Arizona.
Cyrus was seen sporting a noticeable diamond ring on her finger at Muhammad Ali's Celebrity Fight Night XVIII on Saturday.
But alas, those hoping for a Cyrus-Hemsworth wedding will be disappointed: Although reps for the two stars haven't commented, People magazine cites an anonymous source close to the pair who says they're not engaged.
But that hasn't kept the actress/singer from showing off the huge sparkler.
She tweeted an image of herself wearing it on Thursday, writing "I am soooo obsessed with @jennahipp nail foundations! It looks so chic and classic!" underneath the pic.
Cyrus and Hemsworth - who, of course, had an epic weekend as “Hunger Games” posted the third-best opening weekend ever with $155 million - have been dating off and on for the past three years.
They met on the set of the 2009 romantic flick “The Last Song,” only to break up the following year. They got back together less than a year later.
