Miley Cyrus and Ashley Tisdale have more in common than you think. They both can sing (cue the High School Musical soundtrack here), they're blondies, they're engaged to hot guys, and, most importantly, they're both rocking some serious bling!

Singer Miley got engaged to actor Liam Hemsworth in June 2012, sealing the deal with a 3.5-carat, antique Neil Lane diamond set in an elegant 18-karat gold band. And while the rumor mill has been in full force since their engagement, with talks of the couple postponing their big day, we still, ahem, can't stop ogling at her ring.

On the other hand — yes, the left one — singer and actress Ashley accepted a proposal from musician Christopher French earlier this month. The two got engaged on the 103rd floor of the Empire State Building, and Ashley has been flaunting her cushion-cut sparkler ever since.

Check out the gorgeous rings on these two starlets and let us know which one is more stunning in the comments below. Is it Miley's super unique diamond, or Ashley's classic one? Sound off!
