Demi Lovato has discussed how her collaboration with Cher Lloyd came about.

The pair recently teamed up for the track 'Really Don't Care', which features on the X Factor USA judge's new album 'DEMI'.

Speaking to MTV, Lovato said that her family helped raise the idea of working with the British singer - and it was something she wholeheartedly agreed with. The star said:

"Well first of all, my mom loves Cher Lloyd and my little sister loves Cher Lloyd. And I love her too. She has so much sass and attitude. They were really wanting me to do a duet with her. And so I was thinking who else would be more fun to do a collaboration with than a powerful, sassy attitude-filled girl? And there's just nobody else out there. She fit perfectly on that song."

Lovato added that X Factor colleague LA Reid - whose label signed Lloyd in the US - helped sort out the collaboration.

The singer and Lloyd meanwhile recently performed 'Really Don't Care' live in Mansfield, Massachusetts.
