Atomic Kitten

Atomic Kitten, dubbed "The Kittens" by their fans, were an English Girl Group that formed towards the end of the 90s as an obvious attempt to cash in on the growing Girl Group craze. They had three members to start off with - Natasha Hamilton, Liz McClarnon and Kerry Katona. Initially Heidi Range was set to be in the band in Natasha's place but left due to artistic differences and later joined the Sugababes. Katona also left the band in 2000 and was replaced by Jenny Frost who stayed with the band until the split.

The Kittens were initially only mildly successful, their first album "Right Now" and their first four singles doing poorly. The label was considering dropping them but their manager convinced them to allow the girls to release one last song. This song was "Whole Again" and became their first number 1 single. They were much more successful in Europe, Asia and Australia but didn't quite make it in America. They stayed together until 2004 when they had a mutual split but they have reformed several times for one-off appearances.

Atomic Kitten provides examples of the following tropes:

Author's Saving Throw: After three unsuccessful singles, "Whole Again" was an all-or-nothing deal and it saved the band from being dropped.
Bare Your Midriff: They actually only do this twice in the videos for "Eternal Flame" and "You Are".
Beach Episode: The video for "It's OK" which was filmed in South Africa.
Blonde, Brunette, Redhead: The initial lineup with blonde Kerry, brunette Liz and redhead Natasha. Natasha herself has gone through all three colours.
Bob Haircut: Jenny towards the end.
Break Up Song: Implied with "The Last Goodbye".
British Accents: All three girls were from Liverpool.
The Cameo: Liz and Jenny appeared as themselves in the mockumentary Mike Bassett: England Manager singing the theme song for the World Cup.
Cover Version: Three actually. "Eternal Flame" (originally by The Bangles), "The Tide Is High" (originally by The Paragons) and "Ladies' Night" (originally by Kool & The Gang).
Everyone Loves Blondes: By the end of "Right Now" all three girls were blonde and they were this way for the "Feels So Good" album. Then Natasha dyed her hair black.
Face of the Band: Natasha initially but then all of them became equal.
Freeze-Frame Bonus: In the video for "Love Doesn't Have To Hurt" there is a very quick shot of one of the Kittens watching a TV where another (Liz probably) can be seen climbing out of a pool.
Germans Love David Hasselhoff: The girls were extremely popular in Japan, even having a single released exclusively over there ("Cradle").
Greatest Hits Album
Intercourse with You: "I Want Your Love"
Les Yay: Not that much but it was definitely there.
Love Nostalgia Song: "It's OK" and "Whole Again".
Ms. Fanservice: Jenny seemed to take on this role more than the other two.
No-Hit Wonder: The girls were successful but they certainly wouldn't be as remembered as The Spice Girls, Girls Aloud or The Sugababes.
The Pete Best: Kerry. Then subverted when she's the most well-known these days, though it's more due to scandal than anything else.
Real Life Writes the Plot: In the video for "Eternal Flame" Jenny is mostly lying down for her solo shots. This is because she had tonsilitis while they were filming.
Scenery Porn: The videos for "It's OK" and "The Last Goodbye" are notable examples, being filmed in South Africa and Liverpool respectively.
She's Got Legs: Jenny in the video for "If You Come To Me" is seen stretching her legs out against a reflected surface.
Signature Song: "Whole Again", "The Tide Is High" and "Eternal Flame".
Stripperiffic: A notable aversion for a Girl Group. The girls were always dressed modestly enough and even when they wore revealing outfits in their videos, they weren't that exposed. Though they certainly blurred the line with the video for "If You Come To Me".
Title Track: All their albums. Right Now, Feels So Good and Ladies Night were all album tracks. Feels So Good was the only one not released as a single.
Word Salad Lyrics: "See Ya" has some pretty weird lyrics - "Well there's a great big ocean out there boy and you're not my favourite dish/Because you can see me sinking like I told you so/I need a new direction/But you won't let me go"
