Many of us have had the experience of rifling through old photos, discovering cringe-inducing documentation of questionable fashion choices and forgotten birthday parties.
Not very many of us dig out those snaps and discover we once posed with a 10-year-old future Hollywood star masquerading as a Spice Girl.
Strangely enough, that's just what happened to Bria Madrid, who unearthed a photo of her five-year-old self at a Spice Girls concert with none other than actress Blake Lively.

The adorable shot, taken in 1997, shows little Bria posing with Blake, who is channelling Baby Spice in a blue dress with fur trim, pig tails, and towering platform shoes.
"Found a picture when I was 5 at my first concert #SpiceGirls and took a picture with a girl dressed up as Baby Spice who I just realised now was @blakelively," Bria captioned the photo on Twitter.
It wasn't long until Blake got wind of the trip down memory lane, and posted the photo to her own social media channels.
"Pretending to be someone else... since 1997," she wrote on Instagram, thanking Bria for posting the photo.
"Sorry - not sorry - I tricked you into thinking I was @emmaleebunton."
And just when we all thought our tiny hearts couldn't take a drop more wholesome nostalgia, Baby Spice herself chimed in.
"So cute, you're rocking those pigtails," she replied to Blake.
Now seems like a good time to crack open that dusty box of Kodak moments and check for any celebrity cameos in those snaps of your school trip to Rainbow's End.
