AnnaLynne McCord is moving to Southfork.

The former 90210 star will appear on multiple episodes of Dallas Season 3, Entertainment Tonight confirms, portraying a character on the TNT drama named Heather.

Look for her to possess a troubled ex-husband and to be the mother of a five-year old son. When the former returns, Jesse Metcalf's Christopher will step in and he and Heather will become romantically entangled.

McCord is the second 90210 actress to land a new high profile gig in the last few weeks.

Jessica Stroup (Silver on the aforementioned hit) will come on board The Following this winter as Ryan Hardy's niece.

Dallas Season 3, meanwhile, will premiere in early 2014.
