EVERY WEEKDAY MORNING, DailyEdge.ie rounds up the best of the day’s celebrity dirt – from the top to the very bottom.

Katy Perry was caught rotten lip-syncing on stage in France. She was performing at the NRJ Music Awards on Saturday night when she walked on stage to a mistimed backing track. 

Then, the awards’ host walked on stage, interrupted the performance and made her start all over again. SCARLET.

Sorry, the video hasn’t been made available on mobile. But here’s a GIF of the presenter interrupting a mortified Perry as consolation:

Justin Bieber is retiring from music after his new album. At least, that’s what he told a radio station, sparking despair among teenage ladies and rejoicing among music lovers.

However, it turns out he was joking. Perhaps he was just totally mortified after insisting to a large audience the other night that he ‘f***s b****es’. (TMZ)

Stay classy, Justin. Stay classy. Mark J. Terrill Mark J. Terrill

Boy George got brutally owned by One Direction. While watching their performance on the X Factor at the weekend, he singled out Liam for a dig, tweeting:

To which Liam simply responded:

Tub of Savlon to the Boy George residence, please. (ONTD)

I'M BOY GEORGE. ME. Suzan Suzan
