Clearly, Britney Spears and lil sis Jamie Lynn know there's strength in numbers. The sibs individual music videos both gained enough votes to earn them spots on this week's Top 10 Video Countdown!

Brit clinched the No. 9 spot, while Jamie Lynn came in at No. 10. Miley Cyrus debuted her 'Adore You' video in the No. 8 slot. Holding strong in the top three were Scotty McCreery, Backstreet Boys and Lady Gaga.

It's a new year and we here at PopCrush love a clean slate, so next week the countdown is getting a shake-up! We'll only be featuring videos that premiered on or after Nov. 1, 2013. That means the competition is getting a lot tougher, so be sure to vote often to keep your favorite artists at the top!

The poll will be open until 3PM ET on Thursday, so make sure to vote for your 10 favorite videos once an hour. We’ll announce the new champs of the PopCrush Top 10 Video Countdown on Jan. 9 after 4PM ET!
