London: DJ and producer Mark Ronson, who has had great success working with the likes of Amy Winehouse, is currently collaborating with singer Candie Payne. But girlfriend Daisy Lowe doesn't seem too happy.

According to thesun.co.uk, the relationship has come under strain as Lowe feels "seriously left out" with Ronson and Payne sharing a close working relationship. They are working on her second album "I Wish I Could Have Loved You More".

A source said: "When he works on a project, he submerges himself in it completely. He is concentrating all his attention on Payne and Lowe is feeling seriously left out."
