In the photo, Tisdale is wearing a leather jacket and gray T-shirt, her face hidden behind her new layered bob haircut. The former Disney star's blonde cut adds her to the growing list of celebs going shorter for summer; Kaley Cuoco, Minka Kelly, Hilary Duff, Whitney Port and more have also recently cut their hair.
"@nikkilee901 cut my hair off! #summerready," the 28-year-old singer and actress captioned the pic.
Tisdale is gearing up for her upcoming nuptials to musician Christopher French. The High School Musical alum recently celebrated her bachelorette party in Miami, Fla., with close pals like Vanessa Hudgens.
"Weekend with my girls," Tisdale captioned a pic of herself wearing a "bachelorette" sash, along with the hashtag "#turnup4TIZ."
French popped the question back in August 2013, on the 103rd floor of the Empire State Building in NYC.
