What other famous faces were spotted out and about?
Katy Perry, 27, had a ghoulish girls' night out at the 4th annual Haunted Hayride at Griffith Park in Los Angeles. The "Wide Awake" singer spent time there with actress Lucy Hale and Modern Family’s Sarah Hyland.
Meanwhile, Cameron Diaz enjoyed some retail therapy in New York City over the weekend. The Bad Teacher star couldn’t get started on her shopping spree without a steaming cup of joe to keep her warm.
Diaz just celebrated the big 4-0 on August 30 and is welcoming the milestone.
“Getting older is the best part of life,” she told Esquire's November issue, on stands Oct. 4. “I feel better at 40 than I did at 25.” And with age also comes wisdom: “I know more than I’ve ever known,” she added. “I have gratitude. I know myself better. I feel more capable than ever.”
