These are the pictures that will break axed Sugababe Keisha Buchanan’s heart.

Dressed in sexy bondage-inspired outfits, her former bandmates Amelle Berrabah and Heidi Range and her replacement Jade Ewen were spotted shooting the raunchy video for their next single About A Girl.

Hours after announcing the news on Twitter, the 24-year-old headed out to the Red Bull Fashion Factory party in London on Monday night.

But after attempting to put on a brave face, she was reduced to tears in the middle of the party and had to be comforted by Oritse Williams of JLS.

Just two weeks ago, at a gig in London’s Movida, Keisha talked exclusively to MailOnline about how she had been preparing to shoot the new video, which was being filmed yesterday without her in the Santa Clarita desert just outside of LA.

The founding member of the group revealed she had given up junk food and her love of KFC to get in shape to shoot the song, produced by RedOne who has also worked with Lady Gaga.

It was on that night that rumours of a rift between the girls surfaced after Amelle failed to show up, leaving Keisha and Heidi to sing as a duo.

At the time Keisha said Amelle’s no-show was down to a close friend of hers being involved in a car crash.

But the rumour mill went into overdrive and just days later reports suggested that Amelle had quit the group following a bust-up with Keisha.

According to reports, the Sugababes’ management had this week been auditioning new members behind Keisha’s back and re-recording her vocals which feature on the group’s upcoming album Sweet 7.

It is expectedly to be hastily re-worked with Jade’s vocals before its release on November 23.

Reports in today’s Sun newspaper also suggest that Heidi was the chief plotter behind the events which tore the band apart.

The publication claimed the 26-year-old brokered a secret deal with Amelle, 25, to see off Keisha over fears her headstrong nature could cause problems as they promoted their music Stateside.

A source told the newspaper: ‘Keisha clashed with Amelle since she joined. Heidi did not want to be in a position where a big bust-up might arise while they’re promoting their material Stateside.

‘So she persuaded management a less headstrong character would be better suited to the group.’

Speaking of Keisha’s breakdown on Monday night, a source at the London Fashion Week party, in New Oxford Street, said: ‘Michelle Williams [of Destiny’s Child] was the first to share words of encouragement.

‘But it all got too much for Keisha, who started to cry in the middle of the party and Oritse from JLS had to comfort her.

‘It was heartbreaking. She felt devastated about what happened and thinks everyone thinks she’s a b***h when she did everything she could to make it work between her and Heidi and Amelle.’

Keisha’s Sugababe replacement, 21-year-old Jade Ewen, was poached from her own record label a week ago, despite releasing her single My Man only yesterday. Jade will join Amelle and Heidi Range.

A source said: ‘Jade was approached by the Sugababes’ record label Island last week and pretty much bundled onto a plane to LA on the same day, where they were shooting the next video.’

Jade represented the UK in this year’s Eurovision Song Contest, singing My Time. The source added: ‘Her profile’s pretty big since Eurovision, but she felt she couldn’t say no.

‘Her own record label didn’t even know she had gone, so were getting panicky.’
Posting a message on Twitter, Buchanan, who has been in the band for 11 years, said: ‘Although it was not my choice to leave, it’s time to enter a new chapter in my life.’

Your thoughts?

Dear Friends,

I’m sad to say that I am no longer apart of the Sugababes.

I’ve had a great time and have achieved more then I ever thought I would.

Although it was not my choice to leave, it’s time to enter a new chapter in my life
I have nothing but positive things to say about the girls and I wish them the best of luck.

I would like to state that there were no arguments, bullying or anything of the sort that lead to this.

Sometimes a break down in communication and lack of trust can result in many different things.

I would also like to point out that I have always supported the girls and they have also supported me.

Remember my drunk pictures out with Amelle, supporting her on her success with Tinchy Stryder… Oh the shame… But what a fun night we had

Now I’m going to take some time to focus on me. I’ve been in this band for 11 years and I have achieved so much.

I have a great family and friends who are behind me 100% and at the age of 24, I’m now going out into this world on my own…

Although im nervous… I’m still very excited on what lies ahead. 🙂

I want to thank the Sugababes fans and my fans for all your support and all who have never judged me, but excepted me for who I am…The feisty, funny, professional, fearless, motor mouth… lol

This is not the end… but the beginning!!!!

Thank you always… Keisha xxx

*UPDATE 2* The plot thickens… News of the World editor Dan Wotten has taken to his Twitter account to spill the beans on some of the behind the scenes drama that has been popping off:

HUGE BREAKING NEWS: KEISHA WILL LEAVE THE SUGABABES. JADE EWEN WILL REPLACE HER. SHE HAD NO IDEA.

KEISHA DID NOT KNOW WHEN I SPOKE TO HER ON SATURDAY. SHE ONLY FOUND OUT THIS EVENING.

I HAVE SPOKEN TO KEISHA. SHE’S OK.

Keisha was booted out of her own band. She is the voice of this band. I feel her treatment has been DISGUSTING. She did EVERYTHING she could.

The Sugababes management were auditioning members and re–recording the album in LA this week BEHIND KEISHA’S BACK. WTF???

She reached out to both Amelle and Heidi. Attempted to find out how she could change to make this work. She had never been cautioned before.

Keisha was told that Amelle is now the Sugababes. How deluded is that? She’s the voice of the band, she wrote the songs. This is WRONG.

I can report Island Records have bn supportive of Keisha. That’s the good news. This was driven by Heidi, Amelle and the band’s management.

Keisha stayed in LA to try and work this out. She was prepared to make compromises to the girls so the line-up could stay in tact.

I must stress Keisha was NOT lying to me on Saturday evening when she said Jade was not joining the band. She did not know at that point.

The management didn’t want a member who could speak for herself and would not be muzzled. That does NOT make her a bully. I know that.

I believe management were not happy with my interview with Keisha telling the TRUTH about Amelle’s disappearance – http://tinyurl.com/pg47w3

Keisha caught the plane to LA with Heidi. They kissed at the airport. But Heidi did NOT stick up for her after all these years.

Keisha is best mates with Leona Lewis. We all know Leona would not be friend with a bully, no way.

Keisha stayed the night at Amelle’s house just three weeks ago. Why would you let your ‘bully’ stay the night?
