Selena Gomez and Justin Bieber: Look who's wearing a ring

Looks like things might be getting more serious between teen heartthrobs Justin Bieber and Selena Gomez. And this time a ring is involved.

On Monday (Feb. 13), Gomez posted a photo on her Instagram page of the happy couple holding hands. But what was on Gomez's finger was the big surprise - a ring with something that sure looks like diamonds in the shape of the letter "J."

Gomez writes, "I'm finally home :)"

The two had split for a while while Gomez toured with her band through South America. As for what this ring means for the future of Bieber and Gomez, only time will tell.
