Nine months after showcasing her famous curves in a black Victoria Beckham dress, Katherine Jenkins has dug out the creation again.

Performing at the Argentina versus Canada pre-World Cup friendly football game in Buenos Aires, the Welsh mezzo-soprano took to the pitch in the figure-hugging £1,500 dress.

As part of her South American tour, the 29-year-old sang the Canadian national anthem before kick-off and also got to meet Argentina's head coach, football legend Diego Maradona.

Jenkins more commonly pictured in dowdy rugby jersey belting out Bread Of Heaven at Wales' home rugby internationals, but clearly enjoyed her trip.

Writing on her Twitter page, Jenkins enthused: 'Standing in the middle of an empty River Plate Stadium, Buenos Aires, about to start my soundcheck. Very VERY cool...

'Mexican wave in the River Plate stadium... I just met Diego Maradona!'

Jenkins is scheduled to return to the UK next month to kick off this summer's festival season.

Jenkins was a notable absence at the Classical Brit Awards earlier this month because she was performing in Germany.

Over the summer, she will perform at the Hampton Court Palace Festival and Cheltenham Racecourse, as well as her own solo gigs.

Earlier this year, she performed a 12-date tour of Britain, which saw her performing acrobatics in addition to her usual soaring vocals.

Jenkins recently denied reports that New Zealand soprano Dame Kiri Te Kanawa had dismissed her as a 'serious' classical singer.

Te Kanawa was quoted as saying: 'We should talk about serious classical singers if you want to stick to the subject,' when asked about Jenkins.

However, the Welsh singer said: 'Dame Kiri didn’t say that. We’re very friendly.'

Unfortunately, relations with the Canadian national team might take some repairing.

After she belted out O Canada, the proceeded to get torn apart 5-0.
