Gilmore Girls' Lauren Graham is in talks for NBC's upcoming drama series Parenthood, replacing Maura Tierney who starred in the pilot.

According to The Hollywood Reporter, Helen Hunt was originally approached to step in for Tierney, but a deal could not be made.

On Parenthood, a contemporary take on Ron Howard's 1989 movie, Graham joins an already strong cast.

The UMS/Imagine TV series, created by Jason Katims, revolves around four adult siblings (Peter Krause, Erika Christensen, Dax Shepard, Graham) and their parents (Bonnie Bedelia and Craig T. Nelson).

Tierney pulled out of Parenthood in September to focus on her breast cancer treatments.

Parenthood was slated for a fall launch but pushed to midseason after Tierney's illness was discovered in July.
