Now that fans of Private Practice met Sam Bennett’s sister last season, it’s time to meet the family matriarch.

And the woman who will play Taye Diggs’ mother this fall is…

Alfre Woodard!

EW has learned exclusively that the veteran actor who is set to play Ouiser in Lifetime’s remake of Steel Magnolias will guest star on the ABC drama as Bennett’s (Diggs) mom. Her episode will air in November.

Private Practice returns on Sept. 25.

Woodard’s most recent credits include a recurring role on True Blood as Lafayette’s mom Ruby Jean. She’s also guest-starred on Grey’s Anatomy, Shonda Rhimes’ other drama for ABC.

Steel Magnolias, which also features Queen Latifah and Phylicia Rashad, premieres Oct. 7 on Lifetime.

Thanks! Alison
