There's some big news coming out of NYCC this morning. Riverdale has announced that Season 3 will be a family affair as Jughead's mother and sister arrive to shake things up. Gina Gershon and Trinity Likins will recur as Gladys Jones and Jellybean, aka JB Jones, respectfully.

Riverdale Season 3 will be all about keeping up with the Jones. Fans of Riverdale will learn a little bit more about Jughead's family in these new episodes, as his mother and sister wreck havoc with their own sneaky behavior. Gina Gershon (Bound) and newcomer Trinity Likins have been set as Gladys Jones and Jellybean. They will debut on Riverdale during the Wednesday, December 12, 2018, episode at 8/7c on The CW.

Gina Gershon plays Jughead's mother, Gladys Jones, a "businesswoman" who runs the salvage yard (chop shop) that doubles as a Serpent compound, and the Serpents all snap to attention when she gives them an order. A Serpent with a GED, she acts as Fagin to a crew of teenaged car parts thieves.

Trinity Likins is set for the role of Jughead's sister, Jellybean "JB" Jones. She is wise beyond her years, and her favorite bands are Pink Floyd and Black Sabbath. Jellybean lives with her biker mom in Toledo where they run scams to make ends meet. And like mother like daughter: Jellybean, who goes by JB now, is quite the little con artist herself.

Film, television and stage actor Gina Gershon recently completed a residency at the famed Café Carlyle, where she performed her musical act, Wild Women Don't Get the Blues. Her television credits include FX's Rescue Me, HBO's Curb Your Enthusiasm, Amazon's Red Oaks, and Lifetime's House of Versace. Gershon also won Best Supporting Actress at the Toronto Film Festival for Killer Joe, and she appeared in Face/Off, Bound, and The Player.

On just her third professional audition, newcomer Trinity Likins landed the lead role of Amelia in the Hallmark holiday movie Christmas in the Air. She also recurred as Emma in the CBC miniseries Unspeakable.

Riverdale stars KJ Apa, Lili Reinhart, Camila Mendes, Cole Sprouse, Luke Perry, Mädchen Amick, Marisol Nichols, Madelaine Petsch, Ashleigh Murray, Casey Cott, Mark Consuelos, and Skeet Ulrich.
