Ignore the rumors: singer Leona Lewis is not getting married!

“Leona is definitely not engaged,” her rep tells PEOPLE.

Britain’s tabloids started the gossip when they printed pictures of Lewis wearing a diamond-free band on her wedding finger as she exited London’s Crystal nightclub on Saturday.

But while Lewis has called long-term boyfriend Lou Al-Chamaa “the one” and admitted she d like to get married one day, the “Bleeding Love” singer has no plans to walk up the aisle just yet.

“Leona has worn that ring for years – it is a friendship ring that Lou bought for her as a sign of commitment when they were teenagers,” her rep further explains. “This story does the rounds every now and then.”

Lewis, 23, has been dating Al-Chamaa for five years and first met the 23-year-old electrician when they were nine-year-olds living on the same street in Hackney, East London. They currently share a $250,000 home in London’s Stamford Hill.

On May 9, she became the first British female solo artist to hold a U.S. number one album and single in the same week.

Her album Spirit is also the biggest-selling debut by a female artist since Carrie Underwood’s Some Hearts in 2005 – and scored the biggest digital album sales week ever for a new artist, male or female.
