Backstage buzz at “Today” cranked to MAX when Kathie Lee Gifford’s newbie actress daughter Cassidy, 22, showed up to plug her new horror flick, “The Gallows,” trailed by her very own VIP entourage of PR peeps, stylists and makeup artists – triggering an on-air showdown with Motor-Mouth Mommie, who immediately groused about her li’l girl doing a ghost flick!

“Do a rom-com and we’ll get to go to ITALY,” kackled KLG. Rolling her eyes, Sassy Cassie sighed to Hoda Kotb: “It’s all about her!” … then zinged: “She didn’t come out to Fresno when I was filming!”

When Mommie countered that she’d visited her in Texas for another indie, Darling Daughter daggered: “And you complained the whole time!”

Said a “Today” insider: “Backstage, everyone covered their mouths to stop exploding with laughter! Cass had not only shot bigmouth Kathie down, she’d upstaged her! Coming into her own stardom, she’s not taking crap from anyone –including bossy-pants Mom!”
