As PLL sleuths know, though, one season in Rosewood is like two seasons in Hollywood because the teen drama airs episodes nearly year-round. (Thanks be to 'A'.) But for surprising superfan James Corden, watching 6A, 6B, 7A and 7B simply isn't enough.
"Is this true that next season might be the last? Just true or false. True or false answer," the Late Late Show host interrogated star Lucy Hale as she waffled with her reply.
"It is ending," Hale, 26, said eventually. "I think for the girls – I know you're devastated."
Corden, growing increasingly agitated, spun around in his chair, flailing his arms with disgust.
"What?!" shrieked Corden, 37.
"I know, it's crazy," Hale explained. "We've been doing it for six years. I've literally spent my 20s on the show, and I think that all good things must come to an end. Who knows what could happen. I love that show, I love the people I work with, it's really fun, it's the best job in the world, I, you know, count my blessings every day, I can't believe I get to wake up and do that. But, you know –"
The actress trailed off as a stunned Corden clasped his hand over his mouth.
"Go ahead, what were you going to say?" she asked, laughing. "Are you okay?"

The comedian composed himself and got back to business: "How do you want it to end?"
"I used to say I wanted the show to end walking away in the sunset, they're all happy living an A-free life, like no drama, right? But I don't. I want it to end really tragically," Hale said, smiling.
"Whichever way it ends is a tragedy," Corden stammered indignantly, pretending to tear up. "And you know that."
