Producer Mark Ronson has turned to pal Amy Winehouse for support after splitting from his girlfriend of three years.

Grammy-winner Ronson had been dating American Cosi Theodoli-Braschi since 2005, but the couple parted ways earlier this month.

And the star admits he has been relying on friends like Winehouse to cheer him up.

He says, "It's sad times for me at the moment. I was dating my girlfriend for three years but we split up. I'm lucky I have good friends. Amy has been brilliant and is always there for me - and I'm there for her too."

And Ronson insists his close friendship with the Rehab hitmaker has nothing to do with his love split, again dismissing rumours of a romance with married Winehouse.

He adds, "I am sick of talking about it. Amy is a friend."
