Miley Cyrus in Jenny Packham | Muhammad Ali’s Celebrity Fight Night XIII

Miley Cyrus looked so grown up when she stepped out on the red carpet last night for Muhammad Ali’s Celebrity Fight Night XIII. The 19-year-old was in attendance that night to perform with Kid Rock.

She arrived at the JW Marriot Desert Ridge Resort & Spa in Pheonix, Arizona with her mother Tish Cyrus and her boyfriend Liam Hemsworth, who just came off a world tour to promote “The Hunger Games”.

Back to her look.

Miley wore a pretty peach-colored silk dress — from the Spring 2012 collection by Jenny Packham, with a lace trim detail at the halter-style neckline.

Now, normally I don’t like “mullet dresses”, but there was something very lady-like and sweet about this one — and it wasn’t a sharp cut as far as the high-and-low design went. The maxi skirt opened to give a view of a lace-trim mini.

It’s nice to know that Miley isn’t one dimensional when it comes to the red carpet. I often find myself either loving her look — or not being a fan of it at all. I liked it this time around.

She completed her look with gold jewels, a pair of nude “Lady Peep” open toe platform pumps by Christian Louboutin and a voluminous wavy mane.

Her shorter ‘do definitely makes her look a bit older, don’t you think?

Miley also wore a diamond on her left ring finger which has now sparked rumors of an engagement. We’ll see.
