LADBABY Mum is virtually unrecognisable these days, thanks to the incredible amount of weight she’s lost.

And it was particularly noticeable as she sported skintight workout gear for a post on her Instagram Stories.

The influencer and mum-of-two shared a snap of herself ahead of hitting the , in a zip-up grey top and matching .

She wore a black vest top underneath, and the ensemble clung to her in all the right places.

Mum, aka Roxanne Hoyle, flashed a huge smile at the camera as she held up the peace sign, and added: “There’s always so much to be grateful for in life.”

Her gym session came ahead of Rox celebrating her 42nd birthday on Tuesday, as she posted a video of herself blowing out the candles on her birthday cake.

She then shared a picture of herself in hilarious glasses, two birthday rosettes and holding a 4 and a 2 balloon, as she insisted she’s saying her new age with “utter pride”.

“I’m not apologising… I’m owning it,” she continued.

“Because every single year has shaped me into the woman I am today.

“The mistakes, the lessons, the heartbreaks, the ups, the downs, the wins, the big laughs – they’ve all built a strength, perspective and gratitude that 24-year-old me simply didn’t have yet.”

Rox added that there’s “something so freeing about getting older” and “not feeling like you need to shrink yourself anymore”.

“I don’t want to rewind time. I honestly want to honour it,” she continued.

“Yes, the world might glorify youth but there’s nothing luckier than waking up to another day.

“Another day to love harder, laugh louder, tighter.

“Such a blessing.

“So here’s to embracing every single day instead of wishing the years away. To understanding that ageing isn’t a loss, it’s a privilege!”

Rox celebrated her latest birthday having completely transformed her appearance since last year.

She regularly shares pictures and videos of herself working out in her and husband Mark’s home gym, and heading out in exercise gear.

Why do so many mums love LadBaby's Rox?

THE news that LadBaby - Mark and Roxanne Hoyle - are releasing an autobiography signifies a major career milestone for the pair.

And while they initially found success as a couple, thanks to their harebrained ideas and hilarious pranks on each other, Rox has made a name for herself on her own – and has an incredible 1.3 million followers on her Instagram page.

But what is it that has made Rox so popular with her millions of fans?

I think it’s a combination of her down to earth attitude, her bubbly sense of humour and her expert hacks.

As a mum-of-two myself, I’m always looking for ways to and keep the kids entertained, and rarely does a week go by that Rox doesn’t share a hack to help.

When she shares her hair and beauty tips on her social media, she can guarantee that fans are going to hit the shops in search of the products themselves.

In fact, when she shared a Primark ice face roller recently, I was one of the first to go and grab one, and it’s been a total game changer for my puffy morning skin.

She’s also managed to stay humble despite her and her husband’s rise to fame – a prospect that is much harder than it sounds.

And when it comes to the red carpet events she’s lucky enough to attend, Rox will usually go for a budget high street look rather than a fancy designer number.

However, her exercise posts haven’t negated rumours that Rox’s newly-slim shape is down to taking a .

With an insider telling The Sun previously: “ is currently a very hot topic and people are convinced she’s not being honest about how she’s done it.

“There is a lot of speculation about fat jabs.”

The source added that the “horrendous fat-shaming” Roxanne endured at the height of claims her husband Mark had cheated on her is actually the “tragic” reason behind her
