Okay, we get that kids can't stay kids forever and the internet is rife with 'you'll never believe what so-and-so looks like now' articles, but seriously Tiffany Butcher was like seven, two minutes ago.
Actress Maisie Smith is now 15-years-old and has decided to launch a workout programme called Results 4 Teens. Talking to The Sun recently, Smith said; "I really want to use being in the public eye for good and to encourage people of my age to really understand the importance of getting moving and eating right."
"I have always loved keeping active, especially with yoga, and last year I met [celebrity personal trainer] Cecilia Harris on holiday in Spain. We got chatting about ways I could get stronger and fitter."
"It all started with a couple of training sessions that I posted on Instagram which got hundreds of comments and it was then I realised that so many teens struggle with not only how to keep fit but also the confidence to join in group classes sometimes!"
She added: "I hope I can inspire girls and boys of my age to take these things into their own hands and tackle teen health together!
"At 15, sometimes you feel like you have nothing to do other than school or watch Netflix/play FIFA, so to find a fun way to get fit and strong is a great alternative."
Smith, who played Bianca's daughter Tiffany on EastEnders for seven years, returned to the soap briefly last year for half-sister Stacey's wedding.
The young star has also got a decent singing voice and released her debut single 'Good Thing' last November.
Seriously. We're all officially ANCIENT.
