On Tuesday, Jennifer Aniston wore a pair of stylish summer wedges as she visited a friend in the Hollywood Hills, Los Angeles. In the upcoming month, the 39-year-old actress is set to take part in an hour-long telethon called “Stand Up To Cancer”. This event will be broadcast live and commercial-free on ABC, CBS, and NBC on Sept. 5. Additionally, Christina Applegate, who recently revealed her breast cancer diagnosis, will also be participating in this telethon.
