Rumours that all was not well between the two started earlier this week when 23-year-old Rita stopped following Calvin on Instagram and posted a cryptic message, saying: "Have you ever wondered which hurts the most: Saying something & not wishing you had not, or saying nothing and wishing you had?"

"He's been busy DJing and she's working on her new album and shooting Fifty Shades of Grey.
"Calvin is more private when it comes to fame than Rita, which also played a part. He'd be happy to meet someone who has nothing to do with the industry."
After meeting Calvin last May, the 23-year-old singer said she was 'lucky to have found somebody exactly like me'.
Then in November she gushed: "It's great. It's going well - I'm happy. When something is worth having, you make time for it. When you want something, you make it work."
