Asked if she would have waited to see Bieber, she said: "I mean if it were someone like Whitney Houston I'd be waiting! I'm getting too old to stay up late these days so I don't have a lot of patience for that kind of thing."
On whether she has ever been late for a gig, the star insisted: "My team run this ship like a military. I run a tight, tight ship.
"When you've got a lot of young fans like I do, it's important to be on time. Especially if they have school the next day!"
She's old enough to be his mother though. How is she shading him when she'd naturally be more interested in more mature acts? JB caters to the young/teen girl crowd.
Where is the shade? Because she doesn't want to to watch a teenager grind for a bunch of little girls after being two hours late? Wouldn't it be a bit gross if she said yes?
