Duffy performing live at St Georges Market, Belfast, Northern Ireland - 251108

The All Summer Long rocker has fallen for the Mercy hitmaker's sultry charms, confessing he's a huge fan of her 60s inspired sound.

But the star ruined any chance he had with Duffy - after he told her to keep her distance in case he was unable to control himself.

He tells Britain's Daily Star newspaper, "I did meet her recently, but I told her to stay away from me or she will end up pregnant.

"I like some of the Duffy stuff because it is very nostalgic for me as a Motown fan. It's nice to hear those rhythm and blues grooves with something up-to-date being done over the top. It made me think about doing it myself."
