Um… that’s not Melbourne

BB forgets which city is which

That's not Melbourne!Some one should let the work experience kids out of the video editing studio at Channel Nine. On Sunday night Melbourne viewers were treated to a new Big Brother promo with some not so familiar visuals.

While the ad promised housemates from Melbourne would be on the show, the visuals displayed a backdrop of Perth. Oops.

The video was also posted to the official Big Brother Youtube account without the error being noticed, but was quickly yanked when fans noticed. Luckily, copies are still making their way around the internet. Watch below:
