Sure to surprise and please fans and admirers alike, AnnaLynne McCord of hits series "Nip/Tuck" and "90210" is coming to TNT as a long-lasting guest star on TNT's "Dallas."

TNT announced this evening (October 9) that the 26-year-old vixen will play Heather, a 20-something ranch hand with a troubled ex-husband and a 5-year-old son. 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.

A cursory synopsis of the show tells us that "Dallas" follows the story of "The next generation of the Ewing family - cousins John Ross Ewing and Christopher Ewing - clash over the family's oil business and vast fortune."

In related news, AnnaLynn is hard at work on two upcoming movies, each ready for launch in the coming months, "Gutshot Straight" set for release at the end of 2013, and "Scorned," slated to premiere in 2014.
