X FACTOR star Mary Byrne is tipped to knock Adele off the top spot in the Irish charts.
Sales of the Ballyfermot woman's album are doing better than predicted.
Since her appearance on shopping channel QVC, bosses there say orders are double their original predictions.
And it's good news for Mary in leading retailer HMV, which says pre-orders for the album are flying in.
The CD, called Mine & Yours, is not officially on sale until March 28 -- but it is available to pre-order.
Gennaro Castaldo, spokesman for HMV, told the Herald there had been major public demand for Mary's debut.
"We have had lots of customers coming into the store looking for it and as a result it has been put on the list as one of the largest pre-orders from an artist," he explained. "We are expecting it to be huge and a number one in Ireland."
Furthermore, he said the mum of one could knock current number one selling artist Adele off the top spot. Her album 21 has been number one for seven weeks so far.
"There is a chance that Mary might knock her [Adele] off the top spot for a week or two," he said.
Mary, who finished fourth in last year's X Factor, appeared on QVC last week to plug her CD. QVC UK Director of Marketing Sue Leeson said that the overwhelming sales increase was proof that Mary was going to be a major success in the months to come.
"Clearly our viewers loved her songs and the fact that pre-order sales of her album doubled our targets prove she is going to be a huge success this year."
The album includes the tracks This Is A Man's World and I Who Have Nothing, which Mary performed on The X Factor during her rise to fame.
Mary, who is currently playing to packed out venues on The X Factor tour which is due to finish next month, said of her success: "It's been a great experience and I have to say I would do it 10 times over."
