Since Jennifer Aniston and Vince Vaughn are my fave celeb couple right now, I was really disappointed when I found out they had split. Especially after finding out it was because Vince had cheated on her with some average blonde bimbo. Luckily though, Jen paid a visit to the Oprah show last week (the show airs this week) to confirm that the two ARE still together, so I can breathe a sigh of relief. And here I was thinking their relationship was nothing but a publicity stunt to get people to see The Break-Up.

Seems Jen isn’t the only one denying the break up rumors–her friend Courtney Cox Arquette’s husband David confirmed in an interview as well that the pair are still together, and Vince himself is now suing two British tabloids that claimed he cheated on my favorite “Good Girl.”

People magazine reports:

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.”

Aniston herself said on the episode of The Oprah Winfrey Show airing Oct. 11 that she and Vaughn had not split.

Asked by Winfrey if she and Vaughn had broken up, Aniston answered, “No, no.”
