We finally got our ears on a complete version of Heart by Heart, the X Factor judge's soon-to-be smash hit off the soundtrack to the first Mortal Instruments flick! And it's friggin' AH-Mazing!!! Ch-ch-check out her heart-melting track (above)! Wowz!!! The super talented and totally lovely singer of Fix a Heart, Give Your Heart a Break, and Heart Attack broke ALL the rules with Heart by Heart! Two hearts in one track title? Dammit, Demi — that's crazy enough to work!

While the super talented singer already released her latest album Demi, we get to watch Heart By Heart fuse with the visuals...

Miley Cyrus took a break from putting the finishing touches on her upcoming Bangerz album to answer a phone call in North Hollywood on Thursday.
We really hope it was Liam Hemsworth on the other line!
The 20-year-old wore a rather casual twerking outfit, consisting of a tied-up tee and a pair of American Apparel shorts that were slowly creeping into camel toe country.
Mileybird also had on her gold Cartier bracelet and platform Converse sneakers, which we'd like to think of as her lucky charms.
And of course we can't forget her engagement ring — the sun was shining on it like a spotlight!

Miley...
