Northamptonshire schoolgirl Faryl Smith sung on her biggest stage yet as she performed the national anthem ahead of England's Six Nations match against France at Twickenham.
The Britain's Got Talent star last week released the fastest-selling solo classical debut album yet.
And yesterday she sang God Save The Queen ahead of the match, which England won 34-10.
Faryl's debut album sold 29,200 copies in its first week – the most sales ever for the debut album of a classical singer.
Faryl's dad Tony said the family and the record company had been hoping for the top 20 so they were over the moon with a position just behind U2 and Kelly Clarkson.
Mr Smith said: "We've been told there are already orders for 94,000 copies of her album and they were expecting more today.
"They are predicting that she will get a gold disc award for the album.
"They think in the run-up to Mother's Day the album will sell about 40,000 to 50,000 more copies.
"We're thrilled to bits that it has gone in at number six – it's every singer's dream."
