Hollywood star Jennifer Aniston is teaming up with British celebrity chef Jamie Oliver in new US reality show The Big Give. The former Friends actress struck up a friendship with the Naked Chef host during her marriage to Brad Pitt, when Oliver used to cook for the couple. The Big Give, which will be hosted by Oprah Winfrey, presents 10 people with huge sums of cash with which they will compete to find "the most powerful, sensational, emotional and dramatic ways to give to others". British newspaper The Sun reports Aniston and Oliver will work together in an episode of the programme.
