Aniston's ring row

(BANG) - Jennifer Aniston and Vince Vaughn reportedly had a dramatic row at the London premiere of their new movie.

The former 'Friends' actress apparently angered her actor boyfriend after creating engagement rumours by wearing a ring on her wedding finger to the premiere of 'The Break-Up' on Wednesday night (14.06.06).

When asked about the band, she joked: "It's a 9.5 carat canary diamond Suzy Fabrikant ring. Nice isn't it?"

After hearing the comment, Vaughn reportedly berated her for wearing the ring.

A source told Britain's Daily Star newspaper: "Vince is notoriously private about his personal life and he doesn't want people to know much about their relationship

"He was overhead telling Jennifer it was a 'cheap trick'."

The row allegedly continued at the after-show party held at trendy hangout W'Sens.

One onlooker said the pair barely spoke and Aniston - who revealed she was missing her friend, Courtney Cox's 42nd birthday party to be at the premiere - finally left complaining of a 'headache'.

At a press conference on Thursday (15.06.06), journalists were banned from asking the pair anything about their relationship.
