Rita Ora recorded a number of tracks with Calvin Harris, but he insists the songs cannot be used following their split.
Rita, 23, recorded a number of songs with her former beau - including hit single 'I Will Never Let You Down' - but he's now said that she cannot release any more of the tunes they made together.
A source told The Sun newspaper: ''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)'.
And even without the help of her former boyfriend, Rita will hope to repeat that success when her next album goes on sale.
The Dead's last ever shows will be available online for a fee.
