Fasten your seatbelts, ladies and gentlemen. That “viral” video with flight attendants dancing to Lady Gaga? It’s a fake.

The dance moves are real, and the plane is real, but anyone who thinks this was a bona fide in-flight safety announcement — sorry to burst your bubble.

Doubts about the authenticity of this clip, which has been seen by more than five million Gaga fans so far, were raised in the comments of the Window Seat on Oct. 2. They were echoed this morning in a post by the travel technology blog Tnooz, which accused the airline of pulling a “PR stunt.” (Note: There are several copies of the clip online, which has further deepened suspicions about its origins.)

The airline released a statement about the video in which it assured passengers, “We do not compromise safety in anything we do and it will remain our primary concern.” Apparently, some viewers thought the flight attendants were having too much fun.

You don’t have to be press critic to know this was a manufactured event.

And you’d know it within the first few seconds of viewing this video. The plane is at cruising altitude. Those announcement have to be made before the plane takes off, folks.

Even in the Philippines, where Cebu Pacific is based.

In fact, there’s no excuse for anyone who fell for this video after Oct. 1, when the U.K. Telegraph reported that the video was part of marketing “experiment” by the airline. Here’s what Candice Iyog, vice president of marketing at the carrier, told the newspaper:

This was an experiment that we hope to repeat and also a chance to showcase the talent of some of our cabin crew staff. The performance took place while the plane was at cruising altitude, with the cabin crew giving a normal safety demonstration before take-off.

None of this should take away from the entertainment value of the video, which, even if you think Lady Gaga sucks, is relatively high. Critics notwithstanding.

But is it a real viral video, like Southwest’s rapping flight attendant?

I dunno. Now I’m not even sure if that one was real, come to think of it.
