Jamie Lynn, The New Camila, Gets Stamp Of Approval From Big Sister Britney

Britney might be onto something.

The princess of pop has a couple of shows in Vegas this week, but what's a girl to do in the mean time? Troll Instagram!

Britney hopped onto the gram to share a couple of black and white vintage photos, several SnapChat escapades, a goof ball throwback of her son Jayden and a few snaps from her sister Jamie Lynn's account.

Brit, who famously looked shocked as all hell when Fifth Harmony wasn't immediately eliminated in one of the final rounds on The X Factor back in 2012, gives two thumbs up to JL joining the group as the fifth member (Jamie Lynn initially posted the photo a few weeks ago when the hashtag #BeThe5thChallenge was a thing). It's actually an intriguing idea.

Here's the latest:

My sister is now the fifth member 😜😜😜
