Leona Lewis - American Ad Queen Leona Lewis

Leona Lewis has continued her domination of the US by signing a deal to front a famous advertising campaign.

The 'Happy' singer has become a huge hit in America since releasing her debut album 'Spirit' Stateside in 2008 and has now become the first British star to appear in the commercials for cotton goods firm The Fabric Of Our Lives.

As well as fronting the campaign, Leona will record the firm's theme song with the words: "The touch/ The feel of cotton/ The fabric of our lives."

Many American celebrities have starred in the adverts since they first appeared on US TV screens in 1989, with the first being folk singer Richie Havens.

Leona's involvement is further proof of how big a star she is in America and just how the public there have taken her to their hearts.

Despite her phenomenal success, 24-year-old Leona - who divides her time between her homes in Los Angeles and London - recently admitted she still gets overwhelmed when she meets other famous people.

She said: "I was star-struck when I met Samuel L. Jackson and Daniel Day-Lewis at the Golden Globes. I was excited when I met Nelson Mandela, too. I performed at his birthday in 2008. I was really honoured."
