UK singer Jess Glynne could make music history if her new single tops the charts again this week.
According to the Official Charts Company, her latest song, Don't Be So Hard On Yourself, is racing ahead to top mid-week charts.
If it maintains the top spot until the end of the week, she'll match Cheryl Fernandez-Versini's record of having five number ones on the singles chart as a British solo female.
She has previously had chart success with Rather Be, Hold My Hand, My Love and Not Letting Go.
Last week's number one song, Marvin Gaye by Charlie Puth, has slipped into second position.
Taylor Swift's muso boyfriend, Calvin Harris, holds the third spot with his Disciples' collaboration, How Deep Is Your Love.
