Cox: 'Jen's not engaged'

Courteney Cox has blasted US reports that her best friend Jennifer Aniston is making wedding plans with Vince Vaughn, insisting: "She's not engaged".

American publication Us Weekly printed the story about the couple's mid-air engagement last week, but Aniston's former Friends co-star has told rival Life & Style the reports are untrue.

Asked at a charity event on Monday whether Aniston was planning to wed Vaughn, Cox said: "No, she's not."
