AnnaLynne McCord to guest star on 'Dallas'

LOS ANGELES, Oct. 10 (UPI) -- AnnaLynne McCord has signed on for a multiple-episode, guest-starring role on the Texas-set drama series "Dallas," TNT announced Thursday.

"McCord, most recently seen as Naomi Clark on '90210,' will play Heather, a 20-something ranch hand with a troubled ex-husband and a 5-year-old son," a synopsis said. "Having grown up in a house with four brothers, Heather is quite capable of handling herself around the Southfork ranch hands, but when her ex-husband returns, bringing turmoil back into her life, Christopher steps in, helping Heather resolve the conflict, and the two become involved in a romantic relationship."

Season 3 of the show is to begin this winter.

The series stars Patrick Duffy as Bobby Ewing, senior member of the Ewing family following the death of his older brother, J.R., played by the late Larry Hagman. Linda Gray stars as Sue Ellen, J.R.'s former wife and the mother of his son, John Ross, played by Josh Henderson. Jesse Metcalfe plays Christopher, Bobby's adopted son, who is newly single and determined to make a name for himself and his wealthy family in the world of natural gas.
