Nicole Scherzinger labelled  Alan Carr "stupid" and "dumb", during a live broadcast

Nicole Scherzinger labelled TV chat show host Alan Carr "stupid" and "dumb", during a live broadcast but her spokesperson has since insisted she meant to cause no offence.

The 36-year-old singer thought she was off mic was making the remarks during the 'Stand Up for Cancer' live telethon on Chanel 4.

As the popular host auctioned off items on the show, Nicole - who has previously appeared as a judge on 'The X Factor' - was overheard saying: "He is so stupid."

She later said: "He is so dumb."

Among the items Carr was auctioning off was a cushion once sat on by Hollywood star Channing Tatum, as well as reality TV star Kim Kardashian West's giant thong.

However, a spokesperson for Scherzinger has since tried to downplay the incident, insisting Nicole was merely using "urban slang" and her remarks were not intended in an offensive way.

 "It's urban slang for when something is funny."

The spokesperson added: "Nicole was laughing when she said it and did not say it in offensive way. She is a big fan of Alan and was catching up with him after the show backstage."
