Wanna hear a secret? No, not the Oprah/Law of Attraction kind. But the juicy, exclusive, behind-the-scenes kind, from an insider who offers insight into the much-buzzed-about "Grey's Anatomy" spinoff.

ABC and creator Shonda Rhimes have been so hush-hush about the "enhanced" two-hour "Grey's" May episode — which will introduce a new life for Dr. Addison Forbes Montgomery — that during a development presentation with advertisers last week, the cast members of the new show were on stage but were not allowed to divulge details.

So we will:

Following her disastrous romantic misfortunes, Addison (Kate Walsh) travels to Southern California to seek advice from her old medical school pals, Naomi (Merrin Dungey) and Jackson (Taye Diggs), whom she believes have it all: a beautiful teenage daughter, a great marriage and a highly successful health cooperative. Addison quickly learns that Jackson, also a successful TV health guru, has divorced Naomi.

Addison also meets the rest of the gang at the cooperative — a widowed alternative-medicine doctor, a self-doubting therapist and a male gynecologist who knows little about women — and concludes that while the personal lives of the people around her may be a mess, professionally they stand out. (Sounds like those crazy interns, right?) So she decides to leave Seattle Grace behind and join the Oceanside Wellness Group team.

Oh, if we only knew the title.
