Kaley Cuoco has a short new 'do! 

The "Big Bang Theory" star debuted her much shorter tresses over the weekend with a series of cute Instagram snaps. 

Making a funny face for the candid photo, the actress posed with her blonde locks styled in loose waves, falling right below her chin.

"I can't stop! @clsymonds," she captioned the shot of her stylish haircut. 

The 28-year-old also posted a photo of hairdresser Christine Symonds getting ready to cut the actress' long blonde tresses, and captioned the pic, "This.is.happening. @clsymonds."  

We're loving Kayley's new look -- it's perfect for summer! What do you think of Cuoco's short 'do?
