BBC Breakfast's Jon Kay was left baffled after a 'mystery voice' gate crashed the show and talked over Nina Warhurst.
Nina, 42, was co-hosting the show alongside Jon, 53, instead of Sally Nugent who was absent for the second day running.
The pair presented a wide range of news and topics during BBC Breakfast but in the final half an hour, there was a technical glitch.
As the camera came back to the pair after a previous segment, Nina started talking to viewers.
But she couldn't be heard as a mystery woman's voice came on saying: "What do you think? Does this dress work?"
Another woman was heard replying: "I think it looks good, why wouldn't it work?"

Production bosses quickly realised the blunder and cut the sound, before an oblivious Nina was heard speaking.
As she finished her sentence, a baffled Jon then said: "I think we might have had a strange bit of sound going on there."
Nina replied: "I didn't know if it was just in my head."
Ever the professionals, the pair then carried on with updating viewers on the latest headlines.

Sharing the clip after the programme had ended, Jon wrote: "#BBCBreakfast is now available with added dubbing and voiceovers [crying with laughter emoji].
"No idea what happened here. Whose voice is it?? (but the dress did work, @NinaWarhurst [wink emoji])."
Nina then retweeted her colleague and joked: "The voices. The voices in my head. They escaped."
BBC Breakfast airs daily from 6am on BBC One.
