They called time on their seemingly faultless year-long romance earlier this month.
And while the reason behind Calvin Harris and Rita Ora’s apparently sudden split had, until now, been unknown, it’s been claimed the Scottish DJ ended the couple’s relationship because the singer made a secret trip to Los Angeles.
The music producer was reportedly left unimpressed when his then-girlfriend appeared vague about her whereabouts when the pair flew into the US for separate visits at the same time – and was left furious when he coincidentally used the same driver as the I Will Never Let You Down hitmaker.
A source told The Sun: ‘It all ended when the driver suggested to Calvin that he had taken Rita to a hotel two days earlier instead of driving her to stay with him.’
The Acceptable in the 80s hitmaker was said to be suspicious that Rita had even hidden in her make-up artist’s hotel room for the day to avoid being photographed in public, which would have alerted Calvin to her presence.
But Rita appeared to make her feelings known on Monday night, when she enjoyed an evening in with her pals – while sporting a rather offensive motif jumper.
Proudly showing off the lewd garment on her Instagram page, the 23-year-old singer seeemed to be having the time of her life as she larked around with her friends.
Alongside one shot, she wrote: ‘Cooking for the family.’
Rita addressed her split from Calvin for the first time last week, insisting via her Twitter page she has ‘moved on’ from the Scottish DJ.
The singer took to the social networking site to make a series of posts about her relationship woes, telling her 3.66million followers that she had an ‘incredible time’ with the 30-year-old producer.
Writing on her Twitter page, she said: ‘I don’t usually address speculation but I’ve had an incredible time w Calvin,& i will treasure the memories.
‘I’ve moved on from this topic so i hope people will respect that and do the same. Life can only be understood backwards but it must be lived forwards.(sic)’
Rita was said to have been left rather red-faced after learning that her relationship with Calvin Harris was over via Twitter.
The Scottish DJ took to the social networking site over the weekend to announce the couple’s year-long romance was over, but it’s been claimed the I Will Never Let You Down hitmaker was unaware her beau was going to release the statement.
A source told The Sun: ‘Rita was left embarrassed when he tweeted that it was all over. She didn’t think he was going to make the announcement, so she was shocked.’
After being spotted out and about in Hollywood with a series of women over the past few weeks, Calvin, 30, took to his Twitter page to address the rumour mill.
He wrote: ‘To address speculation – myself and Rita ended our relationship some time ago. She is a beautiful, talented woman & I wish her all the best. (sic)
The couple – who collaborated on number one smash hit I Will Never Let You Down – first split in January for a couple of weeks.
Rita, 23, had also been seen partying and cosying up to other men in Instagram photographs and spent time been in Mexico with friends, including R&B singer Khalil Amir Sharieff, who was arrested in Miami with Justin Bieber earlier this year for drag racing.
The source said: ‘It was Calvin’s decision to end the relationship. They had been arguing for months and had grown apart. She was constantly posting snaps of her with other groups of friends and her trip to Mexico and photos of her with Khalil were the final straw.
‘Calvin likes more privacy than Rita and he hated the extra attention that came with being her boyfriend.’
Meanwhile, Justin Bieber is said to have been a factor in the couple’s split, with TMZ reporting the Baby hitmaker’s amorous behaviour in a recording studio a few months ago was the catalyst for the end of their romance.
A source told the website: ‘Word got back to Calvin, Justin and Rita got touchy feely with each other while they were in the recording studio together over the last few months. From rob kardashian to Calvin Harris wonder whose next on the list.
