Kid Sisters Lennon and Maisy Sing Another Amazing Cover (Video)

YouTube sensations Lennon and Maisy are at it again! The Stella sisters, Lennon (12) and Maisy (8), first caught my eye with their amazing cover of Jason Mraz's hit "I Won't Give Up" . Their latest  YouTube video is a beautifully haunting version of Imogen Heap's "Headlock". Check it out out after the jump!

Seriously, where'd these girls learn to sing with so much soul? You'd swear these little ladies just had their hearts broken ... and then you remember they're not even teenagers yet!

With so much talent, we'll definitely be seeing more of the Stella sisters soon-- and not just on YouTube! Lennon and Maisy announcied via Twitter that they'll  be joining the cast of ABC's drama "Nashville", set to air in the fall and starring  Connie Britton and Hayden Panettiere.
