There's no concealing it! Demi Lovato suffers make-up malfunction after forgetting to blend white powder under her eyes

She's been working around the clock to promote her latest album, Confident. 

So it's no surprise Demi Lovato has reached for the concealer in a bid to hide her no doubt tired eyes, though it looked like the 23-year-old beauty slightly overdone it during a night out in New York City on Wednesday.

Surrounded by photographers with unforgiving flashes, the bright lights brought attention to Demi's powdery white under-eyes which sat against her otherwise bronzed skin and rouged cheeks.

Apart from her beauty blunder, Demi looked very demure as she stepped out in New York on Wednesday night.

The former Disney star left her out-there ensembles at home for a look which was perfect for the unpredictable nature of fall.

The Cool For The Summer hit-maker headed out in a pair of dark skinny leg jeans with a white top under a white cardigan that featured a cascading neckline.

By wearing lots of layers, the star ensured she was perfectly comfortable outside and could quickly adjust for warmer inside temperatures if needed.

Kick around in Demi's Valentino ankle boots

Autumn is here so start packing away your summer clothes and start planning your look for the coming season.

As well as a winter coat, bag and cosy knits you'll be in need of a new pair of boots. And if the over-the-knee trend is just not your cup of tea then stick to an ankle boot for easy seasonal dressing.

Need inspiration? Then take a look at Demi Lovato. The pop starlet was spotted out and about yesterday in a pair of oh so cool booties by Valentino. These are a seriously covetable buy and feature the signature Rockstud embellishment on the slender straps. Swoon.

If you're feeling flush then click (right) to buy a pair now at MATCHESFASHION.COM and wear with skinny jeans or with your 1970s floaty midi dress (another AW15 essential). But for those without the A-list sized budget we've picked out some very similar boots that will do the trick without breaking the bank.

It has been a big week for Demi, with the former child star dropping her new video for latest single.

The clip is an action packed three minutes filled with guns, explosion and some pretty intense fighting between her and actress Michelle Rodriguez.
