Jesse Metcalfe says the "rivalry" between him and Josh Henderson helped with their Dallas fight scenes.

The stars both appeared in Desperate Housewives and now portray warring cousins in the reboot of the US TV show Dallas. Jesse is Christopher Ewing while Josh is John Ross Jr. Ewing and the pair drew on life experiences for their roles.

"We often auditioned for the same roles in our younger years, so there was a definite rivalry between us which lends itself to the fight scenes. But we've built up a good friendship now," Jesse told Closer magazine.

Jesse was famed for his chiselled body while in Desperate Housewives and also shows off his rippling muscles in Dallas. He admits feeling nervous this time around.

"Christopher's very passionate and there is a love story, so expect a lot of bedroom scenes!" he laughed. "The pressure was on for my body to look good, so I worked out like a crazy man for two to three hours a day."
