Vince Vaughn denies split with Jennifer Aniston

Vince Vaughn is making it clear that he's still devoted to Jennifer Aniston: He's threatening to sue several tabloid newspapers that alleged he was seen kissing a "mystery blonde" and had ended his relationship with Aniston.

In a statement released by the London law firm Schillings, Vaughn – described by his attorneys as the "Hollywood actor, also known for being the partner of Jennifer Aniston" – is said to be filing a "legal complaint" against "The Sun and Daily Mirror newspapers … and the New York Post."

Vaughn complains that papers "published allegations that he was caught kissing a mystery blonde whilst attending a charity event on Sunday -Oct. 8- at London's Old Vic theatre. Mr Vaughn will say that the articles suggested that he was unfaithful to Ms Aniston, with whom he had allegedly ended his relationship only a week before."

The statement continues, "Ms. Aniston and Mr. Vaughn had not ended their relationship either at the material time or since. … The suggestion that he was having a passionate embrace and kiss, or has ever been unfaithful to Ms. Aniston, are false."

According to the statement from Vaughn's attorneys, "The case is expected to go to jury trial in London's High Court in 2007, if it does not settle earlier."
