Kaley Cuoco has debuted a bold new pixie-style haircut, having opted to chop her long blonde hair in favour of something a little edgier. The Big Bang Theory's actress surprised her followers when she revealed her new 'do via Instagram but was immediately congratulated for her daring yet winning new look.

"Thank you @clsymonds for bringing out my inner Peter Pan :) #byronbeverlyhills #justcutitoff," the 28 year-old captioned the multi-photo frame showing off her sophisticated new style and giving a shot out to the Byron Williams salon in Beverly Hills.

It seems that hairstylist Christine Symonds has earned the actress' trust: after styling Cuoco's choppy bob haircut at the end of April, she gave the star her latest confident chop. That salon-fresh feeling was too good for Kaley to waste so she went out with her husband Ryan Sweeting, her sister Briana, and a couple of pals to catch Bruno Mars' concert with Pharrell Williams at the Hollywood Bowl.

"Best night at the bowl!! #pharrell #brunomars #happy" she wrote when posting a collage of the evening and showing how was she working her new cut whilst out-and-about.

Kaley's haircut is the latest in a line of image modifications the comedy star has made since marrying the tennis star. In March she flaunted freshly inked Roman numerals of her weddings date on her upper back, which matches that of Ryan's forearm tattoo, before she had her trademark blonde surfer locks cut into a bob.
