The battling blondes of "Knot's Landing" are back.

The stars of CBS' long-running primetime soap are reunite for this Sunday's "Oprah: Where Are They Now?," and we have an exclusive clip.

The episode features stars Joan Van Ark, Donna Mills and Antonio Sabato, Jr.
 
"Knot's" was a spin-off of the legendary "Dallas," and aired from 1979 to 1993. Throughout its run, it also starred Nicollette Sheridan, William Devane, Michelle Lee, and many others.

At the reunion, Van Ark and Mills reveal that they were always good pals offscreen, discuss the ups and downs of plastic surgery, and talk a bit about their personal lives.

In the exclusive clip at the top of the page, Mills gets teary-eyed discussing her adopted daughter, Chloe Mills.

Model-turned-actor Sabato, Jr. also opens up, discussing his Italian heritage and his arrival in the U.S. at age 13.

Keeping the episode in soap land, Oprah also talks to Candy Spelling, who was married to  legendary producer Aaron Spelling ("Charlie's Angels," "Melrose Place") for 38 years, and has had a publicly rocky relationship with their daughter Tori, best know for her role on "Beverly Hills 90210."
