Although Calvin was working on Rita's upcoming album while they were together, he has reportedly offered tunes he wrote for her to the 22-year-old singer who is hoping to relaunch her career three years after her debut single 'Happiness'.
A source told the Daily Mirror newspaper: ''Alexis has an amazing voice that works really well with house music, she's a fan of the genre and hoping to put new material out soon.''
This is more bad news for Rita, 23, who recorded a number of songs with her former beau - including hit single 'I Will Never Let You Down' before Calvin, 30, insisted she cannot release any more of the tunes they made together.
A source previously said: ''Rita's album has hit a bit of a road block after Calvin pulled all the songs he had worked on for the project before they split.
''He'd made a lot of songs for her but they're now likely to go to other artists.''
It's been reported that the pair made at least a dozen tracks together, which were to represent the bulk of the eagerly-awaited record.
The source added: ''Calvin wants a clean break, personally and professionally. He's already given her one massive hit so doesn't feel her owes her.
''He doesn't want to be linked to her, especially now she's in a new relationship with Rich Hilfiger.''
Rita's first studio album, Ora, was released in 2012 and spawned a number of huge hits, including 'RIP' and 'How We Do (Party)'.
