American hitmaker Jason Derulo is set to continue with his chart reign this week after 'Talk Dirty' has managed to hold onto its No.1 position during today's midway update. 

The single is currently outselling its closest competitor, which is Katy Perry's 'Roar', by 7,500 copies and if he maintains his lead until this coming Sunday when the positions are confirmed he will spend a second week at the top with the raunchy track. 

'Talk Dirty' has since become Derulo's fastest-selling single to date and is also the fourth fastest-selling single of the year. Elsewhere in the Top 40, OneRepublic's 'Counting Stars' is at No.3, Haim's 'The Wire' is at No.14, and Demi Lovato's inspiring anthem 'Skyscraper' is at 17. 

Lady Gaga's 'Applause' is now at No.18, Kings of Leon's 'Supersoaker' is at No.36 while their new record 'Mechanical Bull' debuted at No.1 today on the albums chart, and CHVRCHES 'The Mother We Share' is at No.40.
