Josie Gibson is celebrating going from a size 18 to a 12 in just nine weeks.
The 34-year-old gave birth to her first child, a son Reggie, in September 2018.
And now the Big Brother star has shown off her impressive weight loss on Instagram by posting a before and after picture.
She captioned the snap, ''Bye bye back fat!!! Sorry you have to see this! I’m so nearly there, I have my waist back and it feels amazing.''
She continued, ''I only want to be a size 12!! I haven’t put a lot of pressure on myself and I have not exercised like I used to but it’s coming off. Big thanks to the @dotheunthinkableuk team!! I’ve been having meals delivered and it works out £1.90 a meal with training plans to follow (which I’ve been a bit s**t at) But I’ve gone from a Size 18 – 12/14 in 9 weeks (I had birthday and Christmas off!) oi oi has to be done."
Her fans were thrilled for her achievements.
One said, ''Josie, you look amazing! Hard work is paying off.''
While another wrote, ''Well done you. Back fat is worse than the obvious what I can see fat. Diet and exercise is hard work but...a little effort goes a long way...looking super!''
This comes after she had split from her boyfriend Terry at Christmas.
Josie told new! magazine that the couple had separated after they had a row over her shoes.
She said, ''He’s got OCD and just after Christmas, he went mad about too many of my shoes being in the hallway. So I kicked off and said, ‘Well, we’ll go then!’ and he went, ‘Alright!’ and bagged up our stuff. So Reggie and me headed to a hotel.''
She continued, ''Two days before New Year's Eve, me and Reggie stayed in a hotel for two nights before going to my house. It was the worst New Year's Eve ever. I’d never go back now. I need somewhere secure for me and Reg.''
Well done to her for going down the dress sizes - we hope her and Reg have a wonderful 2019 together.
