how the famous faces transformed in the limelight
Holly Willougby has made a name for herself in the limelight thanks to her regular TV spots, on everything from This Morning to Surprise Surprise and Celebrity Juice.
But she looked totally different when she first started out, and we've caught a glimpse of her all those years ago in the video for S Club 7: Artistic Differences.
And she's not alone - there's a whole stream of Child Stars
who look very different now.
Some have barely changed in the last few decades and seem to have found the key to eternal youth. Others are proof that it's possible to grow out of those awkward teenage years.
Here are more former child stars who look really different now...
She shot to fame playing the twins in Parent Trap - but seeing Lindsay now, she couldn't have changed more through the years.

He might be one of the most well known pop stars across the globe now, but do you remember Justin way back when?
The star appeared on the TV shows Star Search and The All-New Mickey Mouse Club as a child, before rising to prominence as one of the two lead vocalists of NSYNC in the 1990s.
Megan McKenna has become somewhat of a reality queen in a matter of months - but she wasn't always so cool and collected.
The TOWIE star previously auditioned for Britain's Got Talent, and looked VERY different in her earlier singing career as part of band double act Harmony.
She's gone on to find fame in girl group The Saturdays, but Frankie (known at the time as Sandford) first shot to fame as part of S Club Juniors in 2001.
How could we forget?
Frankie was joined in S Club Juniors by a younger and very sweet Rochelle.
She took on the role of bushy-haired Hermione Granger in the Harry Potter films - and look at Emma now.

Well he now looks like this - and has gone on to star in films including Nebraska and Blue Ruin.
Dustin Diamond and Mark Paul Gosselaar
They shot to fame on Saved By The Bell - but you wouldn't recognise these two now.
Dustin has gone on to star in TV shows, as well as causing controversy with an alleged sex tape, while Mark-Paul went on to star in Franklin & Bash, NYPD Blue and more.
He is best known as a child star in films such as Jerry Maguire, Stuart Little, The Little Vampire, and more.

We can't lie, we miss that shocked face.
