Time for some shots: Pitbull, Ke$ha 'Timber' hits No. 1 in the US, Katy Perry 'Dark Horse' jumps to top 10 [VIDEOS]

It's going down. Pitbull and Ke$ha's new country/rap hybrid single "Timber" has reached No. 1 on the Billboard Hot 100.

According to Billboard, the shots-influenced song has finally eclipsed Eminem and Rihanna's "The Monster" after that single sat at the top of the charts for four weeks with "Timber" waiting patiently below it.

"Timber" rises to No. 1 thanks to a fourth week on top of the Digital Songs chart, with 301,000 copies sold. The track also made gains on the Streaming Songs chart, sitting at No. 2 and it also gained on the On-Demand Songs Chart and Radio Songs.

The rise of "Timber" unfortunately follows the news that Ke$ha has entered rehab for an eating disorder, though this news gives her something to celebrate. "Timber" marks Ke$ha's third No. 1 on the Hot 100 and Pitbull's second.

OneRepublic's "Counting Stars" bypasses "The Monster" and rises one spot to No. 2 after four weeks at No. 3. This makes "Counting Stars" a tie for OneRepublic's best-performing song, with its 2007 hit "Apologize" also peaking in the second spot.

Meanwhile, "The Monster" has finally been chased from the chart's apex and sits at No. 3.

Nos. 4 and 5 hold steady with Lorde's "Royals" and A Great Big World's "Say Something" keeping their spots from last week.

A newly announced single is the lone debut in the Hot 100 this week, as Katy Perry's dark horse of a song "Dark Horse" launches to No. 6. The third official single from Prism easily bypassed Perry's personal favorite track "Unconditionally," which peaked at No. 14.

"Dark Horse" (feat. Juicy J) marks Perry's 13th top 10 single.

The bottom of the Hot 100 is full of familiar fare. Passenger's "Let Her Go" remains at No. 7, Avicii's "Wake Me Up!" rose two spots back to No. 8, Miley Cyrus' "Wrecking Ball" returns to the top 10 at No. 9 and Imagine Dragons' "Demons" stumbles down four spots to finish things off at No. 10.
