Wait until you see what a Hollywood makeover did to this X Factor girl group

FIFTH Harmony first broke onto the music scene in 2012, placing third in the US' second series of The X Factor.

   TV NEWBIES: The girls appeared on the US X Factor back in 2012

But since their appearance on the hit show, the songstresses have overhauled their look almost beyond recognition.

Gone are the mismatched high street outfits, dodgy extensions and questionable makeup choices.

Now the girls are serving A-list Hollywood glam in floor-length gowns, with immaculate hair and makeup to rival the Kardashians.

Need proof? Look no further than the cover of their new album, 7/27.

   GLAMAZONS: The girls have been completely transformed by Syco stylists

Draped in silk, sequins, faux fur and skyscraper heels, the girls may be posing in the desert, but they look as though they've just sashayed off the red carpet.

Camila rocks a silver pleated number and golden tresses for a look that's equal parts VIP and vixen.

Ally serves seriously luxe vibes in a bejewelled cape, silver cuffs and power bun, topped off with a classic red lip.

   FINALISTS: The girls finished third on the show's second series

Normani vamps it up in a red, off-the-shoulder peplum dress that flaunts thigh and cleavage to sizzling effect and channels Cleopatra with a chic, blunt fringe.

Meanwhile Lauren could pass for Kylie Jenner with her statement brown lip, bedazzled, figure-hugging gown and tousled brunette tresses.

And Dinah looks every bit the old school screen siren in a shimmering peach, satin gown and white ruff.

   BEFORE THE FAME: The girls used to look more high street than high fashion

It's certainly a far cry from the leggings, denim shorts and biker boots they wore for their small screen debut.

After nailing the UK charts with Worth It, something tells us their next single, Work From Home, is going to serve up more sex appeal than ever before.
