SONS OF ANARCHY star Katey Sagal blatantly snubbed Geena Davis by denying on national TV that they ever worked together – and now sources say the two actresses are engaged in a nasty feud.

On a recent segment of Bravo’s “Watch What Happens Live,” host Andy Cohen began questioning Katey about famous stars she’d shared a spotlight with, including Bette Midler, Bob Dylan and her “Married with Children” co-stars Ed O’Neill and Christina Applegate. But when Andy asked a tongue-in-cheek question about what Geena “smelled like,” Katey replied: “I don’t know Geena Davis.”

Undeterred, Andy noted that Katey appeared as a guest star on TV’s short-lived “Geena Davis Show” in 2001.

Buts still Katey denied it.

 The reaction made the host squirm, and he produced a photo of the two actresses appearing together on Geena’s old show.

At that point, Katey just shrugged and laughed the whole thing off.

“Katey’s reaction was a slap in the face to Geena,” a Hollywood insider told The ENQUIRER.

“Her attitude was like, ‘Oh Please. Who is this nobody Geena Davis?’”

But Geena, now 57, was one of the hottest young actresses of the late ’80s and early ’90s. She appeared in a string of hit films including “Thelma & Louise,” “A League of Their Own” and “Beetlejuice” – and she won an Oscar for Best Supporting Actress in the 1988 drama, “The Accidental Tourist.”

The insider says Geena was so infuriated by Katey’s slight, she ranted to a pal: “How dare she try to humiliate me on television. Katey was damn glad to get the work on my show. She wasn’t doing much in those days.”

After “Married with Children,” Katey’s career sputtered until 2008, when a whole new TV generation discovered her on the FX series “Anarchy.” In the show about the members of a motorcycle club, she plays tough mama Gemma Morrow.

But the source believes that Katey’s been a little too tough on Geena.

“Katey owes Geena an apology,” concluded the source. “No one wants to be forgotten by a peer.”
