Chris and Liam Hemsworth unrecognisable in throwback snap

There’s nothing like whipping out the old photo album at your parent’s place for a guaranteed trip down memory lane, though many of us look so different these days we would struggle to pick ourselves out of a kindy school line up.

Looks like that’s a problem that extends to celebrity households as well, with our favourite actors, singers and stars regularly sharing jaw-dropping childhood snaps that prove everyone starts somewhere.

The latest in the unrecognisable celebrity throwback is a couple of hunky Aussies who fans could barely pic in a very sweet photo shared to Instagram.

It’s none other than Aussie megastars Chris and Liam Hemsworth, looking pre-Hollywood chic in their primary school uniforms.

Shared by big brother Chris, or Thor as he would grow up to be, to celebrate Liam’s birthday the photo was an absolute hit with fans, more than 3 million of whom gave the photo a like.

It seems, however, the photo may have been more recent than we thought, with Chris cheekily alluding to a little known later in life transformation the duo allegedly underwent in the caption.

“Happy birthday @liamhemsworth this photo was taken 3 years ago today, damn time flies but you haven’t changed a bit,” Chris joked.

Celebs confuse fans with unrecognisable throwbacks

It comes as plenty of celebs hop on the early life photo trend, some causing more of a stir than others.

Earlier in the week, Instagram model and fitness entrepreneur Tammy Hembrow left fans gobsmacked by sharing some unseen snaps of herself from her younger years, before she found fame and fortune as a fashion and fitness business owner.

She might only be 26-years-old now, but the Aussie influencer is barely recognisable in the throwback pics of her as a teenager, taken prior to ‘getting into fitness’.

In one pic she shared to her Instagram Stories during a fan Q&A on Tuesday, the mum-of-two is seen wearing a black boob tube top and matching black leggings while posing for a mirror selfie in her ‘old’ bathroom.

Tammy’s makeup is more subtle than what she tends to favour these days, and her hair is a warmer, natural blonde.
