Little Mix star Leigh-Anne Pinnock got caught out when she told an x-rated story to her bandmate without realising the microphone above her was catching every word.

The UK pop singer and her band mates Jesy Nelson, Jade Thirlwall and Perrie Edwards were doing a live stream interview with Refinery29 when the slip up happened.

The reporter asked them if there was something they would never do again and Pinnock said: "Oh, I know exactly what I'd say but it's definitely too explicit."

The others joined in laughing with Thirlwall adding, "I know what you're thinking".

However Nelson needed clarification so Pinnock leaned over and, according to The Sun, whispered: "Anal".

That's when Edwards interrupted pointing out: "Babe, you know there's a microphone right above your head?"

Things moved on smoothly enough afterwards but it was definitely an awkward moment.
