Some work: Holly (here in September 2015) paid tribute to her hard work on her 12 week fat loss guide

On the left, the brunette wore suspenders with a lacy bra and bottoms set, while in a second picture to the right, Holly was shooting her summer bikini body.

It seems that the first was taken for a sexy ZOO magazine photoshoot in June 2014 while the other was originally posted on Holly's Instagram 48 weeks ago.

Looking sensational in both snapshots, the star showed the greatest change at her waist but also in her chest after she was forced to have a breast lift after the weight loss.  

Of her £6k surgery spend, the 23-year-old is said to have spent £4,500 on a reduction from FF cups to a modest size C to ensure her breasts were in proportion with her newly-trim figure. 

Unrecognisable: Geordie Shore star Holly (left) wasnn't letting any criticism over her looks get to her last week, hitting back at one Facebook user who scorned at her plastic surgery in a photo she shared with Charlotte Crosby (right)

Criticism: A Facebook user commented on Holly's photo that they could 'see the plastic surgery a mile off,' prompting a quick quip from the reality star

Holly also shocked fans last week when she shared a look at her visibly fuller pout, hitting back at criticism over her changing looks by reminding fans that it was 'bloody expensive.'

When one user scorned her because she didn't even 'look like the same people anymore,' Holly quipped 'I hope so, it was bloody expensive x'.

After further criticism over a photo with Geordie pal Charlotte Crosby, Holly also replied: 'No airbrushing, I just lost weight thanks'.

The Geordie Shore star was also bombarded with questions about her lips after posting a close up selfie of her fuller pout, with some commenters suggesting that she had artificially altered her appearance
