Demi Lovato looked very grown up on the red carpet at the 2011 Latin Grammy Awards which took place in Las Vegas, Nevada, last night.

The 19-year-old singer/actress wore a Roland Mouret Compeyson zip-front stretch-crepe gown with a very deep plunging neckline.

Her berry gown is actually being worn back to front.

You can see from the Net-A-Porter model that the plunge is at the back and the zipper is at the front.

No doubt the young star wanted to go for maximum impact on the red carpet, hence the gown reversal, but it’s a tad long for her.

Whilst the reversal is not a first on the red carpet, it is genius on this occasion unlike her hair which is tragic.

Ombre hair has been growing on me, but this is the very worst showchasing of this trend I have seen on the red carpet.

I do however love her glossy red lips. It’s such a shame that her hair let her down on this occasion.

You can buy Demi’s Roland Mouret gown from
Net-A-Porter US and Net-A-Porter International.
