Selena Gomez and Justin Bieber: Engaged?

Justin Bieber and Selena Gomez look tired as they arrive in Mexico. Selena flashes a ring on her engagement finger, one which she was not wearing when she boarded the flight in LA.NON- EXCLUSIVE December 07, 2011. (Bauer Griffin)more pics After Selena Gomez was spotted in Mexico wearing a ring on her engagement finger, we couldn't help but wonder if she and Justin Bieber have some big news to share.

Is Selena Gomez engaged to Justin Bieber? We don't know. But we do know she was sporting a ring on her engagment finger in Mexico. (Bauer Griffin)
Although it may feel like he's lived a few lifetimes, The Biebs is only 17-years-old. So we don't exactly think he has any need to rush into an egagement -- even if Gomez is 19. That said, the couple do look fantastic together, and we'd love to see them start a family somewhere down the line.

When Gomez boarded her flight to Mexico in LA yesterday, she didn't have a ring on her finger. Then, when she emerged south of the border, she was showing one off. And while we don't believe it's a diamond, the placement on her engagement finger makes this quite the riveting tale.

One thing's for sure, if Bieber and Gomez do get engaged, millions of Beliebers will cry, the earth's foundation will shake, and tabloids will have one hell of! a field day. Of course, for Gomez's sake, we hope Bieber could find a more romantic way to propose to his girlfriend than while flying in a jet.
