Strictly Come Dancing 2020 viewers confessed to feeling a little old when EastEnders' Tiffany Butcher actress Maisie Smith made her debut on the BBC series.
The show officially launched on Saturday night, as the 12 pairings were confirmed for the first time.
Maisie was excited to learn who she would be dancing with, before learning her professional dance partner was Gorka Marquez.
But viewers were stunned when she made her appearance, with many not having seen her since her younger days on EastEnders.
She's played Tiffany on the show since she was six years old, while she did take a break away for a few years.
Maisie returned as Tiff full-time in 2018, and remains on the show as Bianca Jackson's daughter.
When Maisie was little, fans couldn't get over how cute she was with her character being a hilarious part of the show.
Years on, and stunning Maisie looks so grown up - something some viewers couldn't get over.
As Strictly showed a throwback to her childhood days, many confessed they hadn't seen EastEnders since then.
Even just seeing the comparison to Maisie then and now left many viewers feeling "ancient", over how much she had changed.
Taking to Twitter, one fan said: "OMG I haven’t seen Eastenders in about eight years and I’m like this over the fact that is little Tiffany."
Another said: "Tiffany is so grown up - all Strictly is doing today is making me feel ancient."
A third added: "It makes me feel old that shes 19 tho. She was wee when I watched Eastenders."
Meanwhile, a fourth said: "#Strictly havent seen eastenders for years didnt recognise little tiffany."
Strictly Come Dancing airs Saturdays and Sundays on BBC One.
