The Hello hitmaker was performing at the AccorHotels Arena in Bercy on Friday (10Jun16), the same day as tournament hosts France played Romania at the Stade de France in the capital.

Impressing her French fans, she projected the game on the big screens in the arena to wild applause and cheers. "How many of you want France to win the Euros?” Adele asked the crowd. "I really want France to win the Euros - I think you lot deserve it!"

While it's unlikely that she played the whole 90-minute match, in which France won 2-1, her gesture went down a storm as fans took to Twitter to praise the star.

Earlier this week (beg06Jun16), Adele hit headlines when she was criticised by legendary music producer Tony Visconti, who questioned whether her soulful voice is the result of studio trickery.

The 72-year-old, who produced many of the late David Bowie's most famous albums, believes that modern production techniques are so advanced that it is impossible to tell whether Adele's voice is naturally as strong as it sounds in her hits like Hello.

"You turn the radio on and it's fluff - you are listening to 90 per cent computerised voices," he told Britain's Daily Star newspaper. "We know Adele has a great voice but it's even questionable if that is actually her voice or how much has been manipulated. We don't know."

Adele later rubbished the claims, and reportedly called the producer a "d***head". In a clip uploaded onto Twitter on Friday by a fan at a recent concert, the singer can be heard saying, "Some d***head tried to say that my voice was not me on record... suck my d***. Why don't you come to a show, my darling?"
