Electro kingpin Calvin Harris will enlist the help of past collaborator and Florence and the MAChine leading lady Florence Welch on his upcoming single. 'Sweet Nothing' will be released tomorrow (July 29th 2012) as the follow-up to the Example-featuring 'We'll Be Coming Back.'

Harris and Welch had previously collaborated together on Florence's last single, and first number one, 'Spectrum (Say My Name)'. The 'Acceptable in the 80's' hit maker provided a remix for Florence's track and the single has spent the last two weeks as the UK's Number One, largely down to the sales of Harris's remix.

In a recent interview with Q Magazine Harris admitted that he has received interest from Rihanna to spark up a friendship, after the two worked together on the hit 'Where Have You Been All My Life.'

Despite the single shooting to number one, the Scot has admitted that he is still too shy to accept the Bajan's offers of friendship. He explained in the interview: "She's like, 'yeah come on and hang out in my dressing room'. I'm like, 'Arrghh!. I mean what do I say to Rihanna? There's nothing! She's great, she's well friendly, she's nice, I see that. But.I can't. I'm from Dumfries, man!"
