Let's do the time warp! The most jaw-dropping celebrity throwback photos

It looks like Hamish has always had a passion for cakes! Taking to Instagram with his adorable throwback from 1988, the TV host and dad called his 5th birthday a "possible cake making genesis moment."

He wrote: "Mum just found this pic of my 5th birthday cake: cricketers playing a fielder-less game on a giant 5. Whilst it would be easy to nit pick here and say there should be some green coconut for grass, and some small fireworks on the edge could give it a real BBL feel, I distinctly remember loving this cake so much. It blew my mind that my loves of cricket, chocolate and my new age could be combined."

Giving fans a little Easter treat was Dannii Minogue, who shared a previously unseen photo of herself with sister Kylie when they were kids.

"This pic is me and @KylieMinogue cooking up a storm at our Nain's house when we were little. What will you be whipping up for Easter this year and will your little ones be giving you a hand in the kitchen?" she wrote.

In a message to all the kids, mums and dads starting the first day of school, Dannii Minogue shared a sweet photo of her own first day at school. What a cutie!

Personal trainer Tiffiny Hall posted this old photo of herself in high school, sharing the one piece of advice she'd give her teenage self.

"I was so passionate in school and had such incredible support from my teachers. I didn't realise at the time how important that was, but I feel so grateful now for where it has got me in life. If I could give my teen self one piece of advice? It'd be to enjoy the journey and not worry so much about the future. Live in the moment, back yourself, and trust that kindness, hard work, positivity and passion are the key to success."

We love that message!

I try very hard to be grateful and appreciative all year, but it doesn't hurt to have one dedicated day," the actress confessed.

"My #TBT is going way back #BodyBeforeBaby I wouldn't trade my kids for anything, but once in a while it's ok to be envious of what you used to look like. #Goals #Dreaming This also reminds me...I need a vacation," Sarah Michelle Gellar wrote next to this heavenly pic with husband Freddie Prinze Jr.
