We used to live for their noughties' style, dodgy (we mean PINNACLE OF COOL hair-cuts and ultimate squad goals. And tbh, we still miss those glory days.
Can you believe it's been over 18 years since Kerry Katona first left the iconic girl group?
We're still in shock, too.
And it feels just like yesterday that our favourite girl band split for good in 2004.
It still makes us cry if we think too hard about it, but (hopefully) seeing their journey through stardom can make us whole again.
CHECK OUT: Where are Atomic Kitten now?
Atomic Kitten WATN - STACKED
Glam girl band Atomic Kitten were formed in 1998, but it wasn't until 1999 that their unforgettable debut single 'Right Now' landed in the UK Top 10 music charts. They split in 2004, but came back on stage for a reunion in 2014. Check out where each of the band members are now...
Founding member Kerry Katona broke all of our hearts when she announced her decision to leave the band to focus on marriage and family. She wed Westlife singer Brian McFadden in 2002, with whom she shares her eldest daughters, Molly Marie and Lilly-Sue.
The next decade for Kerry involved becoming the queen of supermarket chain Iceland, then losing lots of money (weep), a string of unhappy marriages and alleged drunk binges - ahem, who remembers THAT infamous 2008 This Morning Interview? But by 2018, the mum-of-four had turned her life around and in 2019, she was even ready to look for love again, appearing on Celebs Go Dating. Alas, Kerry didn't find the one during her time on the show, but she is currently bossing life as a working mum. Go, Kerry.
While she's not as regular a telly guest as the likes of her fellow band members, Liz McClarnon has still starred in Celebrity Masterchef (which she won with her delicious dishes) and remains in the TV and music industry. Keeping a low profile eh, Liz?
Jenny from the block had been a member of the girl band Precious before she replaced Kerry Katona in 2001, when she was just 23. The singer stuck with the band until their split in 2004.
After she ditched the er, very sheer tops and parted ways from Atomic Kitten, Jenny Frost developed a successful career as a TV presenter across hit shows like BBC 3's 'Snog Marry Avoid' - who else remembers this legendary makeover show?
Natasha joined Atomic Kitten in 1999, replacing original band member Heidi Range - who was with the group before any songs were released. The original mutl-tasking mum, Natasha even decided to take her baby with her on the 2003 tour with Atomic Kitten. Absolute goals.
Since the '00s, Natasha Hamilton has been doing the rounds on the celebrity television circuit, with appearances on Celebrity Come Dine With Me, Celebrity Big Brother and First Dates. Plus, she's now a mummy to four kids - and she followed in Gwyneth Paltrow's footsteps by eating her placenta.

The tide is high but we're holding on (to a future reunion). We're not the kind of girl that will give up just like that.
Besides, Atomic Kitten did in fact come together in 2017 for a short-lived reunion.
They were touring UK nightclubs and holiday camps when drama broke out and halted their plans.
Kerry Katona allegedly called co-star Natasha Hamilton a "toxic c***" during a drunken rant.

The drunken rant marked the awkward end of the the girl group's reunion and second shot at fame.
Kerry later confirmed reports when she tweeted, "Was very proud to be the founder member of AK! Had some amazing times with the kittens!
"And gutted not to be a part of that no more! I guess I’ll keep to knock knock jokes from now on!"
Does this light-hearted tweet mean there's still hope for the future? Or are we only dreaming? Is this burning an eternal flame?
