Attention, Upper East Siders: Rufus and Lily are back in town.

"Gossip Girl" stars Matthew Settle and Kelly Rutherford
-- who had an on-again off-again relationship throughout all six seasons of the CW series -- are headed to Lifetime's original movie "A Sister's Nightmare," also starring Petyon List and Natasha Henstridge.

Lifetime has described "A Sister's Nightmare" as centering on "an intense sibling rivalry and dark family secrets. After fifteen years of hospitalization for being criminally insane, Cassidy (Henstridge) is finally released and reenters the life of her younger sister, Jane (Rutherford). But when a dangerous rivalry and past familiarities return, Jane is unable to prove her sister is still harmful to society and takes matters into her own hands to protect her family."

Although "Gossip Girl" has been off the air for nearly eight months, Rutherford admitted to having her fingers crossed for a "Gossip Girl" movie.

"Hopefully [creators Stephanie Savage and Josh Schwartz] left it open for a great movie and we'll all come back and have fun," the actress told Clevver TV, adding that she "would [sign on and do it]. It would be so much fun."

If Rutherford gets her way, there could be more than one Rufus-Lily reunion in the cards.

"A Sister's Nightmare" will air on premiere on Saturday, September 7 at 8 p.m. ET on Lifetime.
