Larry Hagman has cancer.

The 80-year-old actor - who has reprised his conniving character J.R. Ewing for a reboot of TV series 'Dallas' - revealed his diagnosis in a statement today (14.10.11) but has vowed to continue working.

He said: "As J.R. I could get away with anything - bribery, blackmail and adultery. But I got caught by cancer. I do want everyone to know that it is a very Common and treatable form of cancer. I will be receiving treatment while working on the new 'Dallas' series. I could not think of a better place to be than working on a show I love, with people I love. Besides, as we all know, you can't keep J.R. down!"

Warner Horizon Television and TNT added in their own statement:"Everyone at Warner Horizon Television, TNT and the entire Dallas family completely supports Larry Hagman during this time. We look forward to watching Larry once again work his magic by bringing one of television's most interesting, complex and controversial characters back to the screen in the new Dallas series."

Larry underwent a liver transplant in 1995 after years of heavy drinking
