The 'Big When I Was Little' singer, who is working on the follow-up to her 2013 album 'In Your Hands', dreams of teaming up with the 'Get Lucky' hitmaker and superstar DJ.
Speaking at the Beats by Dr. Dre Drenched in Colour nail event in London last night (24.04.14), she told BANG Showbiz: ''I'd love to work with Pharrell but it's annoying because everyone is working with him now and you don't want to be like, 'Oh, I want to work with you too'. But he is the dream.
''There are loads of people I'm looking to collaborate with that are on my list. Calvin Harris would be cool. I'm in the process of planning my next album but it's early stages at the moment.''
The 26-year-old star went along to the Beats by Dre party, which celebrated the colourful range of Beats Solo headphones, to support friend and model Zara Martin, who was Djing at the event and has been spending time with Calvin's girlfriend Rita Ora in Los Angeles.
Zara said: ''I know Rita, we've hung out in LA and London, it's crazy in America when she's there, when I was there last time she was pretty big, the paparazzi are so prevalent in LA, it's quite scary.
''I do have really good friends who are in the industry but I'm not going to exploit it by feeling like I have to get a picture or a selfie to post on my Instragram.''
The actress thinks it would be tough to recast her character, Winifred Sanderson.
