Miley Cyrus Shows Off Engagement Ring at LAX

Miley Cyrus is happy as can be to be engaged, and she showed it this week. She sported her giant 3.5 carat rock (which you can see clearly above) at LAX, rocking a tight white tank, jeans and shades -- because that bling is pretty blinding.

Cyrus and longtime boyfriend Liam Hemsworth confirmed their engagement on Wednesday (June 6). Hemsworth reportedly popped the question on May 31, much to Cyrus' delight. She told PEOPLE mag, ”I’m so happy to be engaged and look forward to a life of happiness with Liam.” There's no word on a date yet, but the cute couple have been cohabitating for quite a while, sharing a brood of pups between them.

As we mentioned earlier, the 3.5-carat bling is a Neil Lane diamond. A diamond expert states that the diamond ring probably cost Hemsworth about $100,000; the diamond is cushion-cut and set in an “Art-Nouveau” gold band.

The 'Party in the U.S.A.' singer isn't the only Cyrus stoked on the news. Her mom, Tish, and dad, country singer Billy Ray, are beyond thrilled for their little lady's engagement. Both parents took to -- what else? -- Twitter to share their sentiments.

"All I ever hoped for as a Daddy was to see my kids reach their dreams," Billy Ray tweeted, adding, "To find happiness...peace of mind ...and someday know... true love." Awww! Mama Bear Tish gushed, "Wow! All of the love pouring out for Miley and Liam is incredible! So happy for my precious baby girl and the love of her life!"
