LOS ANGELES: Sandra Bullock is opening up! Three years after her split from husband Jesse James, the Oscar-winning star told Vogue magazine that she has no desire to go backward and examine what happened, especially not publicly. “We’re all where we’re supposed to be” and “I’m grateful that I’m here, blessed to have what I have,” she said. At the recent Teen Choice Awards, Sandra, who’s pushing 50, wore a head-turning sequined mini-dress by Antonio Berardi and strappy Casadei heels — and her new vamped-up image comes after a shakeup of her style team. –SS
