Justin Bieber has a lot to love this week - he has his third No. 1 single in the United States. This week, his non-single Purpose cut "Love Yourself" has displaced his former chart-topping single "Sorry" on the Hot 100. Meanwhile, Rihanna's new single "Work" has a big debut after just two days out in the world.

After weeks of organic build up, "Love Yourself" takes over the No. 1 single slot on the Hot 100, Billboard reports. Though "Love Yourself" doesn't dominate sales (No. 3, 116,000 copies sold), radio play (No. 3, 132 million audience impressions) or overall streams (No. 2, 16.4 million plays), his combined point total was enough to overtake "Sorry."

The rise of "Love Yourself" marks Bieber's third No. 1 single (all from Purpose), following "What Do You Mean?" and "Sorry."

And "Sorry" shouldn't be feeling sorry for itself - the single fell just one spot to No. 2.

As the Bieber takeover continues on the charts (he's held the Nos. 1 and 2 spots for two weeks), Twenty One Pilots continue to rise themselves, inching up one position to No. 3 on the charts with 117,000 downloads sold, 120 million audience impressions on radio and 12.7 streams.

Meanwhile, while Adele returns to her rightful spot atop the U.S. album chart, her lead 25 single "Hello" falls down one more spot this week, resting at No. 4.

This week marks a big change for Billboard and its charting metrics, as the company readjusts its formula to lessen the impact of streaming and boost sales. Because of the new measurements, there were massive shakeups in the top 10 of the Hot 100 this week. Flo Rida's latest single "My House" zipped up from No. 12 to No. 5. "My House" seemed to benefit greatly from its sales numbers - it was the fourth-most downloaded track of the week with 98,000 copies sold.

Other tracks that made major leaps on the chart include The Chainsmokers' "Roses," which bumped up from No. 8 to No. 6. Selena Gomez also had a massive chart "Revival" with her new single "Hands to Myself," which shot up 14 spots to No. 7. Gomez seemed to benefit from her sexy (if a little awkward) Saturday Night Live performance, as her new single was majorly boosted in sales (67,000 units), streams (11.5 million plays) and radio (35 million plays).

As "Hands to Myself" rises, Gomez's second Revival single "Same Old Love" falls slightly, down one spot to No. 8.

And though both Flo Rida and Gomez had big gains this week, no artist had as big of a rise as Rihanna, whose lead ANTI single "Work" debuts at No. 9 this week. "Work" led sales with 126,000 copies sold in just a little less than two days. The impact of Rihanna's new album release can't be understated - the single also debuted at No. 27 on radio and was streamed 2.2 million times. Expect a major rise for "Work" next week, as the single has more time to sizzle and be downloaded and played.

And, rounding it all out, we have Alessia Cara's "Here" at No. 10.
