Holly Willoughby has shared a seriously old-school snap of her youth.
The gorgeous blonde replied to a tweet from The London Studios who had shared a photo of the S Club TV gang, which used to air on CITV.
Holly, 36, and This Morning co-host Phillip Schofield were presenting This Morning Live in Birmingham, and it turns out Holly was at the same studios 17 years ago.
"Today @hollywills is at @TMLiveEvent .. 17 years ago she was in Studio 3 for S Club TV on CITV! #ThrowbackThursday @ChildrensITV", said the caption.
Oh, how life comes full circle!
Replying to the image of her 19-year-old self, she simply wrote: "Oh wow!" alongside a heart emoji.
You don't look much older now Holly x
Hundreds of her 7.2million Twitter followers couldn't believe how she hasn't really aged at all.
"You don't look much older now Holly x", said one.
Another sweet fan said: "You look so young and beautiful but you [sic] better now just like wine tastes better with age..."
Way back in 2000, Holly won an audition for S Club TV, in which actors represented an alternative S Club. Shortly after, she ended up appearing in a show called S Club 7: Artistic Differences and played a character called Zoe.
During yesterday's live event, Holly also found out that her dad was working there too!
She couldn't wait to share it with her Instagram followers, and shared a cute pic, writing: "Having a fab day at @thismorning @tmliveevent in Birmingham and look whose [sic] here with me!
"Papa Willoughby is on the @everesthomeimprovements #everest stage... talk about worlds collide! #takeyourdadtoworkday #tmlive xxx"
Her fans noted how young her father Brian looked.
One particular user couldn't help but share her love for Holly's dad: "ERM HOLLY... your Dads a fox...!"
"He's adorable! ", said a second.
Another added: "Your dad looks fab, Holly!"
"Very young looking Hols", said a shocked fan.
Now we know where she gets her looks from!
