Sigala's Sweet Lovin' is challenging Justin Bieber for this week’s Number 1 single

He’s been dominating the chart for weeks, but could Justin Bieber’s reign at the top be over on this week’s Official Singles Chart?

The DJ/producer Sigala's new single Sweet Lovin’ is charging up this week’s Top 40, zooming 66 places to Number 2 on today’s Official Chart Update, just behind Bieber’s current leader Love Yourself. Can he go all the way by Friday?

If Sigala pulls it off, it would be his second chart-topping single following Easy Love, which hit Number 1 back in September.

Meanwhile, Justin Bieber’s Sorry is at Number 3, Adele’s Hello at 4, and Grace ft. G-Eazy’s You Don’t Own Me completes the Top 5.

New entries and high climbers

Coldplay are on their way to score their 16^th Top 10 single this week, as Adventure Of A Lifetime climbs six places to Number 9 today, and Sigma and Rita Ora’s Coming Home vaults from 26 to 11.
