DJ Khaled is heading for his first Official UK Number 1 single with I'm The One featuring Justin Bieber, Quavo, Chance the Rapper and Lil Wayne

The producer's all-star collab featuring Justin Bieber, Chance The Rapper and Lil Wayne is leading the way on the Official Chart Update.

DJ Khaled looks set to make his big UK breakthrough this week as his new single I’m The One heads for Number 1, according today’s Official Singles Chart Update (May 2).

Released last Friday (April 28), the latest all-star collaboration from the Miami-born producer - which features Justin Bieber, Migos member Quavo, Chance the Rapper and Lil Wayne - could become his first UK chart-topper should it hold its position until Friday’s Official Chart reveal.

I’m The One is currently just over 2,000 equivalent sales ahead of last week’s Number 1 single, Clean Bandit’s Symphony ft. Zara Larsson, which slips to 2 today.

Regardless of whether it secures the top spot, I’m The One is all but certain to give Khaled a personal best on the Official Chart; his highest charting single to date is last summer’s For Free ft. Drake, which peaked at 25. Look back at DJ Khaled's complete UK chart history here.
