The singer's second album '21' is currently outselling the rest of the top-5 combined, while single 'Someone Like You' is also top of the single countdown.

Her debut album '19' is also likely to remain at number three, according to the Official Charts Company.

Meanwhile, Hollywood actress Gwyneth Paltrow, who is married to Coldplay's Chris Martin, is set to score her first chart hits.

Paltrow's songs with the Glee cast - a medley of 'Umbrella' and 'Singing In The Rain', and a cover of 'Forget You' by Cee Lo Green - are both inside the top-40.

Winners and performers at the BRIT Awards earlier this month are continuing to enjoy strong sales.
