Miley Cyrus and fiancé Liam Hemsworth (in Ermenegildo Zegna) hit the red carpet in Century City, California, last night for the 8th Annual Australians In Film Breakthrough Awards.

This is the first time the couple have attended an event together since they announced their engagement a few weeks ago.

Flashing her 3.5-carat Neil Lane sparkler, Miley honoured the event by wearing a dress by Australian brand Zimmermann.

The risqué LBD leaves me feeling like she’s wearing a dress with an open top revealing her bra, but the bralet is actually built into the dress.

Miley’s not a kid anymore and while she has been going for more demure red-carpet looks lately, I have to say this sexy LBD totally works for her.

Her hair and makeup, which are often a deal breaker, were flawless on this occasion too.

Christian Louboutin Exvota platform sandals completed her look.
