Post Malone and Camila Cabello are battling for Singles Chart supremacy once again

There big gains so far this week for Marshmello and Ed Sheeran, while Taylor Swift, Liam Payne and Rita Ora are eyeing new entries.

Post Malone is taking some moving from the Official Singles Chart top spot – it looks like his track Rockstar will sit at Number 1 for a fourth week.

The track, which features 21 Savage is 4,000 combined chart sales ahead in today’s Official Chart Update, once again leaving Camila Cabello’s Havana ft. Young Thug at Number 2. Camila did perform Havana at yesterday’s BBC Radio 1’s Teen Awards, however, which may cause an uplift for a track. Watch this space as Post Malone and Camila’s chart rivalry rages on.

Climbing for an 11th straight week, up six places to a midweek position of Number 3, is Marshmello and Khalid’s Silence. The masked DJ/producer has announced his next single will feature Selena Gomez.
