Lady Gaga is on course to score three entries in this week's Top 40, according to midweek sales data from the Official Charts Company.

The popstar released new album CHROMATICA on Friday, the day she hit the top spot in the singles chart with Ariana Grande duet 'Rain On Me'.

Early data suggests that the pair are on track to remain at number one, while another Gaga collaboration, 'Sour Candy' with Korean girl group Blackpink, is currently at 12. The song 'Alice' from the album is at 21.

'I Dunno', from Tion Wayne, Dutchavelli and Stormzy, is set to be this week's highest entry, tracking at 11.

Elsewhere, Topic's dance track 'Breaking Me' continues its stealthy ascent of the chart, rising five places to six after 48 hours of sales.
