The newly-blonde actress shows off a sleek style for the Television Critics Association Press tour – but a few days later, it’s all about sexy volume as she channels Marilyn Monroe on the Golden Globes red carpet.
“I cut my hair two hours ago!” the He’s Just Not That Into You star tells PEOPLE.com of the bob she debuted at an N.Y.C. screening of the film. “I can’t say that it was a big decision. I loved it longer,” she explains. “but it was just time. I kept pulling it up in a ponytail, and I thought, let’s do something else.”
The 90210 actress adds red-carpet polish to her shoulder-length hair by going straight and full at an event in Hollywood. But it was back to her signature corkscrew curls for a celebrity football event in L.A. a few days later.
The singer told PEOPLE.com that ditching her signature blonde waves for a sleek dark brown do was inspired by recent changes in her life. “I’m in a new place in my life and just evolving,” she said, “and I wanted a change.”
