Just days after her movie Ramona and Beezus came out, Selena Gomez lost her voice and had to go on vocal rest -- she even had to cancel her concert at the Delaware State Fair tomorrow.

"This sucks... My throat is sick. I'm not, my throat is. Ugh." Selena Tweeted.

Last night Selena was on Lopez Tonight and communicated with host George Lopez through a computerized talk box and a dry erase board. Take a look:

Send Selena your well wishes for a speedy recovery!
