X Factor judges Simon Cowell and Demi Lovato got to hear their category’s contestants on the show on Wednesday and tonight, it’s Britney Spears and L.A. Reid’s turns!
We previously showed you a clip of Justin Bieber, who’ll be guest mentoring alongside L.A. tonight — but now we have some behind-the-scenes footage!
These clips WON'T be featured on the show tonight, so ENJOY them here before you tune in!
Check out the EXCLUSIVE clip (above) of JB singing, Let It Be, and playing piano for L.A.!
Seems like the Biebs had even MORE downtime in between contestants, as he just couldn’t help but break into song himself!
Take a look at Justin spontaneously singing, Catching Feelings, in L.A.’s Beverly Hills backyard… AFTER THE JUMP!!!
