Yep, it's that time of the week again!
Take a ganders at this snap of Katie back in 2003 as she made her debut at the X Men premiere in London.
The mum-of-five slipped her stunning figure (nothing much has changed there, then) into a teeny tiny cropped top that boasted - what can only be described as sheer, printed curtains - trailing down from the eye-popping white bralet.
Katie teamed her belly-baring look with a pair of khaki bottoms but we definitely can't judge as we're pretty certain the whole of the UK owned a pair of these Lara Croft-inspired cargo pants, too.
Just admit it.
On her feet, Katie donned a pair of heels so pointy, they could have had someone's eye out and she covered up her honey coloured locks - miles away from her sleek new bob - under a puffy khaki cap.
Can we also take a sec to reminisce over itsy bitsy handbags? The smaller they were, the more stylish - and Katie's is barely visible!
When it came to her make-up, Katie let loose with the kohl but her gorgeous green peepers got lost under the smokey look. Thank goodness she now knows how to accentuate her features...
Until next Thursday, guys!
