AP - Paging all tabloids: Be careful about what you write about Vince Vaughn and Jennifer Aniston. According to statement released by a London law firm the 36-year-old actor would be filing a "legal complaint" against a tabloid trio — the New York Post and the Britain-based Daily Mirror and The Sun — that said he was seen kissing a "mystery blonde" at an Oct. 8 charity event in London and had called it quits with Aniston.
