If there’s one thing that all celebrities should know, it’s this: Don’t show up late for an interview with Barbara Walters.

Speaking with Billboard for their October issue, Katy Perry admitted that once, while her marriage to Russell Brand was falling apart, she arrived tardy for an interview with the TV news legend — and Walters was having none of it.

“I shouldn’t have done the interview: I was playing Madison Square Garden that same night, and I knew that the end of my marriage was coming. I was just so exhausted and stressed,” Perry tells the magazine. “I’d prepped everyone that I was running late, but Barbara showed up at the original time anyway.

“When I got there, I apologized immediately, but then she said to me, ‘You know, I’ve only ever waited for one other person this long, and you know that person was? Judy Garland. You know how she turned out, right?’ I was like, ‘Oh, snap! Yes, b****!’ I think it’s the coolest thing that Barbara Walters shaded me,” the “Dark Horse” singer continues. “I just couldn’t tell her as we were sitting down for a mega-interview, ‘Hey, my marriage is falling apart. Give me a break.'”

So, there you have it. Make Babs wait and, apparently, suffer Dorothy’s fate.

Considering the timeline, it seems as though the interview in question would be Perry’s inclusion in Walters’ 2011 Most Fascination People special. Take a look at the interview above and let us know if you can detect any residual shade on Walters’ end.
