NYPD Blue‘s Sharon Lawrence is headed to One Tree Hill for multiple episodes as Julian’s (Austin Nichols) never-before-seen mother, sources confirm to me exclusively.

Although Lawrence’s character does in fact come to town to help with the wedding preparations, there’s no hard evidence to suggest she’s a monster. I mean, she probably is. I just don’t have any proof.

Lawrence—who snagged an Emmy nod in ’09 for playing Izzie’s white-trash mama on Grey’s Anatomy—first appears in episode 6, which is slated to air at the end of October.

One Tree Hill‘s eighth season kicks off Sept. 14.
