Ariana Grande has urged fans not to read too much into her latest collaboration with One Direction star Harry Styles, insisting the two pop singers are just friends.

The Problem hitmaker, who previously dated The Wanted star Nathan Sykes, confirmed reports she and Harry have teamed up on her new track A Little Bit Of Your Heart during an appearance on Australian radio show Smallzy's Surgery on Wednesday (13Aug14), and she's keen to stop gossip before it starts by insisting the studio get together didn't blossom into a romance.

She said, "He is a very, very, very nice boy but I'm not like... He's just a nice friend."

And she told DJ Kent 'Smallzy' Small that her new Styles collaboration is not the romantic song fans might think it is upon first listen.

Grande, who is rumored to be romancing rapper Big Sean, explained, "It's about loving somebody so much that you don't care if you have to share them with somebody else because a little bit of their love is enough for you. Which is absolute bulls**t!"
