The 28-year-old Big Bang Theory star ditched her long locks for a short, layered haircut just a day before she was due to a appear at the Nickelodeon Kids Choice Awards.
"This is happening," Cuoco captioned the first pic of the bunch featuring stylist Christine Symonds cutting her hair.
Cuoco later shared a photo of her "Spring Fresh" new look before posting another image featuring more hair-cutting action.
"I can't stop! @clsymonds," the actress captioned the final picture, which finds her with considerably shorter hair and a pair of scissors next to it.
The last picture, however, might have been an optical illusion as the actress appears to be sporting her hair hitting right below her shoulders in another picture she shared Sunday.
