For the third week in a row, up-and-coming pop singer Ava Max rules the U.K. singles chart with her breakout track "Sweet But Psycho," which is proving to be a powerful tune. Just behind Max comes former chart leader "Thank U, Next" by Ariana Grande. That tune, which is steady in second place, controlled the listing for half a dozen frames.

Up to a new peak of No. 3 is "Nothing Breaks Like a Heart," the latest single from producer, songwriter and musician Mark Ronson. The track, which likely previews an upcoming album, features pop star Miley Cyrus, and it looks like it could go all the way to the top if "Thank U, Next" and "Sweet But Psycho" dip in popularity in the next few weeks. 

Another current hit, Post Malone's "Wow.," rises to a new high point of No. 4. The song has only been present on the chart for three weeks, and with every passing frame, it advances. The song is likely the first single from an upcoming album, which will probably arrive this year. 

Just behind Post Malone comes...Post Malone. The hip-hop star's previous single "Sunflower," which was recorded for the new Spider-Man film, steps down to No. 5. 

U.K.-based hip-hop musician Headie One scores a major coup this week, as his new single "18Hunna," which features fellow U.K. rap favorite Dave, starts its time on the ranking at No. 6. The track is One's first top 10 hit, while Dave has broken into the region once before. Last year, he and Fredo saw their cut "Funky Friday" debut at No. 1, where it held for just one turn.

James Arthur and Anne-Marie's collaborative single "Rewrite the Stars" is up to No. 7, a new best showing. The song was recorded for the revamped, remixed Greatest Showman album, which saw big names put their own spin on songs from the popular film. 

The second new entrant inside the top 10 this week comes from homegrown superstar George Ezra, who sees his current release "Hold My Girl" lift to No. 8. The track is the singer's fifth top 10 and his third from his sophomore album Staying at Tamara's, which is still the second most-popular full-length in the U.K. this week, despite the fact that it is approaching its one year anniversary.

The final two positions inside the top 10 across the pond are filled by Freya Ridings' "Lost Without You" at No. 9 and Halsey's "Without Me" at No. 10, both of which return to the region this time around.
