Leona congratulated by Whitney - Dec 22 2006
X Factor winner Leona Lewis was thrilled to receive a phone call from Whitney Houston congratulating her on winning the show.

Pop icon Whitney apparently became a fan of the 21-year-old songstress after a pal sent her tapes of the singing contest.

When she heard Leona had won, she called to say well done, reports the Daily Mirror.

"Whitney thought Leona was amazing and wished her luck," a source said.

Londoner Leona has also been in touch with American Idol winner Kelly Clarkson, whose hit, A Moment Like This, she has covered for her debut single. Kelly, who won the US contest in 2002, apparently told Leona she loved her version of the track.

The song looks set to be the Christmas No 1 after shifting a whopping 150,000 copies in its first day. Fans flocked to the shops to pick up a copy as soon as it hit the shelves on Wednesday. It had also sold 200,000 downloads before going on sale as a CD.

Leona to sign US contract? Dec 19 2006
X Factor winner Leona Lewis is reportedly about to fly out to the US to sign a £5 million contract across the pond.

The 21-year-old will jet out next Thursday to meet music exec Clive Davis, the man behind Whitney Houston, Dido and Angie Stone, reports the Daily Mirror.

She will be joined by Simon Cowell, her mentor on the show.

"Leona’s X Factor prize is peanuts compared to what Clive is offering," an insider told the paper.

"When Clive called Simon Cowell, he was talking £5 million. Leona and Simon will fly to meet him."

A staggering 12.6million viewers tuned in to watch Leona take the X Factor crown on Saturday night and now bookies have closed their betting on the Christmas No 1, as they fear no one will beat her.

Leona’s single, A Moment Like This, is already estimated to have sold 200,000 downloads. It will be in the shops on Wednesday.

The single is a cover of the No 1 song which Kelly Clarkson released after winning American Idol in 2002.

X Factor title for sensation Leona - Dec 16 2006
Singing sensation Leona Lewis was crowned the winner of the X Factor talent show.

The former waitress’ dream of stardom is a step nearer after she beat rival Ray Quinn in the final of the ITV1 reality show.

Thousands of hopefuls entered the competition but their numbers were whittled down to just two by judges Simon Cowell, Sharon Osbourne, Louis Walsh and the voting public.

A million pound record deal and possible fame awaits Leona, 21, from London, who has dreamed of singing professionally since she was a little girl.
