Calvin Harris has admitted that the success of his Rihanna collaboration 'We Found Love' encouraged more artists to appear on his new album.

The Scottish DJ is unleashing his new record '18 Months' on October 29 and has enlisted a star-studded cast of cameos for good measure, including Ne-Yo and Ellie Goulding.

However, he told MTV News that it wasn't quite so easy to persuade artists to collaborate when he first asked acts nearly two years ago.

He believes, however, that the success of his 2011 Rihanna collaboration 'We Found Love' encouraged more people to say 'yes'. Harris said:

"People at the start of the record, when I was trying to gather some people 18 months ago, said no. Then [they] came back after maybe 16 months, maybe after 'We Found Love', they were interested now. They obviously freed up some time and could do it then."

Speaking about his forthcoming new album, the hitmaker continued: "I got the Rihanna track, I got Kelis, Ne-Yo, I got Example. I got Ellie Goulding, Tinie Tempah, Dizzee Rascal, Florence Welch - that's the new single ['Sweet Nothing']. That's a lot of people. I'm really relying on them to sell it! I've never done that before. Although I've done production [on] the odd track for someone, I've never, for my own albums, I've never really reached out to anyone else. So I wanted to go for it and see how many people I could get on one record."
