It's the question burning the tips of America's tongues: Are Miley Cyrus and Liam Hemsworth still together?

UPDATE: Who can keep it together if these two can't? Miley's rep has confirmed to People that their engagement is officially off. Aw, but they looked so cozy together!

EARLIER:

We rarely see them together anymore. They never talk about each other in public. They've been engaged for well over a year and haven't made any plans yet.

As far as we know, though, Miley and Liam are still an item. Although it'd be typical for these two, we haven't heard about any splits in a minute, either. It's possible that just acting like they don't know each other keeps the spark alive in private.

Although it's pretty funny thinking about Miley doing anything in private, here's what we do know about these two little lovebirds' engagement.

The long engagement doesn't mean anything with these two. Miley has explicitly said that she wants a long engagement, because getting married isn't that important; "it's the promise [Miley and Liam] made to each other" that matters.

Rumors are flying that Liam was "mortified" by Miley's now-infamous VMA performance. But the rumors are just that — rumors. It's possible that he confided to a friend that he was unhappy, but we haven't heard anything straight from Liam.

Rumors are also flying that Miley has taken an interest in bridal magazines. Again, these are just rumors, but it would bode well for things not just being on-again, but great-again.

Liam wasn't at the VMAs. But it wouldn't be the first time these two flew solo to one of their engagements — in fact, it's usually the case. Miley didn't come to any of the Cannes Film Festival Hunger Games: Catching Fire parties with Liam, either. Both stars attended the Teen Choice Awards this year, but not together. It could be a sign of trouble in paradise, or it could be a sign that the couple just keeps things chill like that.

They went hiking together in July. That was over a month ago, but it does appear that they're still doing couple activities in private — even if they don't always stay private.

There are a lot of questions that even we can't answer, though. Are they even still living together? If they are still together, do they have some kind of open arrangement? If they're not living together, does Miley still have all the dogs? We're keeping a really close eye on this, and we'll let you know as soon as we do.
