Liam Hemsworth was ready to propose to his girlfriend Miley Cyrus. But it looks like he may have already!

Miley, 19, posted a photo of her new manicure on Twitter yesterday, but it wasn't the color of her nail polish we were looking at. We couldn't stop staring at the huge diamond ring on her finger!

“I am soooo obsessed with @jennahipp nail foundations! It looks so chic and classic!” Miley Tweeted, along with the picture, which prominently shows off the ring.  

And if Liam did get down on one knee, we're not surprised. An insider told 'OKmagazine' that The Hunger Games hunk, 22, and Miley have been talking about getting engaged for a while now! 

"They're still keeping it a big secret, but they're seriously talking marriage," the source revealed to 'OK magazine'. "Liam is crazy about her." 

Liam just returned to L.A. after promoting The Hunger Games in Europe, Canada and NYC, so maybe all that distance made him realize Miley is the one!
