Before they entered the glitz and glamour of the celebrity world, A-listers were kids too and we've got their childhood snaps. See if you can guess these stars from their family-album pics.
We’ve all got some embarrassing snaps from our childhood and these A-list stars are no different. See if you can guess the celeb from pics of them before they were famous…
This retro family photo gives a little hint about the age of this master of bread, but can you guess who the little boy in the centre grew up to be?
Look very closely...
The beloved Great British Bake Off judge is unrecognisable in the family photo with his great-grandma and cousin, and we're absolutely loving his little outfit!
It looks like he was practising his best stern face for the time when he would be assessing people's signature bakes - he's got it spot on!
Clue: You'd probably know this TV presenter more instantly if you could see the colour of his hair...
Did you get it? It's funny man Leigh, also known as Keith Lemon, of course!
The comedian shared the throwback snap on his Twitter account, and fans couldn't believe their eyes at his transformation. 'Your hair!' one exclaimed, whilst another added 'That is not you!'
Despite the debate, Leigh confirmed that it was in fact him at a mere 16 years old, in 1989. Aww - how times change!
Clue: This Dawson's Creek star is the spitting image of her daughter...
Did you guess right? It's Katie Holmes of course! Actress Katie shared this cute snap of her younger self looking absolutely adorable in dungarees on Instagram.
She wrote alongside the post: 'My overall days #familylove #gratitude?'.
Katie, 37, is best known for her roles in Dawson's Creek and Batman Begins, and will star as former First Lady Jacqueline Kennedy in the TV series, The Kennedys After Camelot next year.
We think she looks almost identical to her 10-year-old daughter Suri Cruise. That fringe is too cute!
Clue: She's a little more at home in the jungle these days...
It's I'm A Celeb presenter Laura Whitmore of course!
The star shared this throwback picture of her school days to her Instagram account with the caption: 'Happy Birthday to my June birthday girls. Two girls that I couldn't live without. Today's birthday girl @dee_moran and for two weeks ago (and still celebrating I hope) @orladoyle85 🎉❤️'
We don't think she's changed much - the blonde beauty is still as fresh-faced! Her fans were quick to compliment her on her youthful looks too, with one commenting: 'You look like a young Kate Moss here!!'
According to reports, Laura has been snapped up by the BBC to appear in this year's Strictly Come Dancing - we'd love to see Laura strutting her stuff on the dance floor!
Clue: It's a good job this little one was practising his kicks early on!
It's baby Becks! Did you get it right?
The father-of-four posted the adorable throwback snap of him and his mum on his Instagram account, writing alongside, 'Happy birthday mum... The most amazing and caring person and someone I've learnt so much from over the years ... No words will ever be enough...'
What a sweetheart!

She mentioned how much both of her daughters - Florence Elsie, seven, and Marnie May, three - look like her younger self, captioning the pic: 'Another old school photo of me .Can see both my girls in that face. Such a lovely feeling.'
Tamzin split with her daughters' father, actor Tom Ellis, in 2013, and said last summer that she was taking time off from acting to concentrate on her daughters.
Clue: We reckon this smiley schoolgirl was a big fan of Saturdays...
Did you guess it? It's popstar and presenter Rochelle Humes!
The mum-of-one posted the snap to her Instagram account, writing, 'Mood.. #BabyRoch This literally looks like a picture of my little one...she does look like her Mumma after all'
Rochelle and husband Marvin are notoriously private when it comes to their daughter Alaia-Mai, so we can't compare the two side by side, but we're sure she's just as gorgeous as her mum!
Clue: This family make us Goggle at the TV box...
It's Scarlett Moffatt and her dad!
Our favourite Gogglebox family shared this adorable #TBT snap to Scarlett's Instagram this week, with the hilarious caption; 'Throw back to when my dad has as much hair on his head as I had on my monobrow.'
Fans of the show will know that Scarlett's dad, Mark, isn't quite so 'blessed' in the hair department these days, but that he's quite the looker... perhaps Scarlett should watch out, there could be a new Instagram star in the family!
Clue: This little lady grew up to be a 'bedazzling' A-list actress...
How could you mistake that grin? It's Liz Hurley of course.
The actress and mum-of-one shared this throwback snap on her Instagram, captioning it simply 'Was I sweet?'
Little Liz might have something of a different hairstyle, but she's barely aged a day otherwise. And you can definitely see where Liz's son Damian gets his looks from!
Clue: This TV presenter was formerly an X Factor contestant!
Picture: YouTube/This Morning
It's Rylan Clark! The cute snap of him as a red-haired child was brought out on This Morning by his fellow presenters to embarrass the Essex boy.
And it looks like it worked! Poor Rylan stormed off stage with a bit of a pink face when he saw the old photo of himself.
However, in true Rylan style he took it well and wasn't really in a mood, as he quickly returned to his seat to laugh about the picture.
Clue: This singer has always been 'the female boss'!
It's a young Tulisa Contostavlos!
The NDubz singer from North London is dressed as Tallulah from the musical Bugsy Malone aged 11.

Tulisa, 27, was most recently a judge on The X Factor alongside music mogul Simon Cowell between 2011-2012, and helped bring pop group Little Mix to fame.
We don't think Tulisa has changed very much over the years - what do you think?

It's a mini Fearne of course! The TV favourite posted the throw back snap with the caption: 'A classic 80's scene. Severe fringe, mullet at the back, brown carpet and a big yellow teapot #minime'.
We're glad to see that although the 80s mullet has gone, the blonde locks have stayed and thank goodness - we can't think of Fearne being any other hair colour! Fearne now has two little ones of her own - Rex Wood, three, and Honey Krissy Wood, seven months. She can often be seen posting snaps of what her and her little family are getting up to on Instagram, from baking and cooking to crafts!
