The pop star was exhausted upon landing in Glasgow after three flights in a gruelling 26-hour journey from Australia - and she lost her temper when security insisted on checking her five suitcases.
She says, "I swear, I never feel more like cattle than when I have to go through airport security. They hate their lives and they hate us for sure.
"By the last flight, the third time going through security, I lost it on a security person."
And she admits her touring schedule is so exhausting she rarely wants to leave her hotels.
She adds, "I am so tired. I'm not even sure if I'll be venturing out today. All I want right now is a shower and then my bed." (PAW/WNTRE/LR)
