Pop star Ellie Goulding has got the final number one of the decade, with her single, River.

Her track knocked LadBaby's I Love Sausage Rolls off the top spot, after just one week on the chart.

She also beat Mariah Carey's classic Christmas hit All I Want For Christmas Is You and Stormzy and Ed Sheeran's new single Own It.
