Jen and Vince Deny Latest Engagement Rumor

Looks like Oprah Winfrey can continue holding off on those $8 million wedding plans--at least for now.

Despite making a joint appearance on Us Weekly's latest cover under the blaring headline, "Vince Proposes! Jen Says Yes!," Jennifer Aniston and Vince Vaughn remain unengaged, according to the former Friends star's rep.

"It is not true--they are not engaged," Stephen Huvane told E! News on Wednesday.

Of course, as Us Weekly was only too happy to point out on its Website, Huvane has a history of issuing denials over reports that later turned out to be accurate.

For example, in November 1999, when Aniston was spotting wearing a diamond sparkler on her left ring finger, Huvane denied that she was engaged to Brad Pitt, claiming the bauble was "not an engagement ring," and he continued to deny that the pair planned to marry up until their June 29, 2000 wedding.

In December 2004, two weeks before Pitt and Aniston announced their split, Huvane maintained that all was well in their union. "They are looking forward to spending the holidays with each other. There is no split. They are fine," he told Us Weekly.

In February 2005, Huvane denied reports that Aniston planned to move back into her former Hollywood Hills home, claiming it had been leased out to Sacha Baron Cohen and Isla Fisher. Lo and behold, the couple was asked to move out that month so that Aniston could move back in later that year.

Finally, when rumors that Aniston and Vaughn were dating first surfaced in July 2005, Huvane denied there was any romantic interest. "Vince is a good friend of Jennifer's. I think the tabloids are so eager to see her with someone romantically that they just make these false assumptions," he told the New York Post.

So, who to believe? The choice is up to you.

As Us Weekly spins it, Aniston reportedly accepted a proposal from her Break-Up costar on June 27, as the couple returned (via private jet, natch) from a nine-day vacation in Puerto Vallarta, Mexico.

A "friend" of the twosome tells Us Weekly that Vaughn intended to pop the question on the beach, but opted for the in-flight proposal at the last minute.

"He was going to propose on the beach during the trip, but he chickened out because he wasn?t sure if she would accept," said "friend" gabbed. "But he knew he was leaving town for awhile, so he just felt he had to ask her before they landed."

The same "friend" also floated the rumor that despite his manly image, Vaughn was nothing but a big ol' romantic at heart.

"Vince almost cries whenever he tells the story of the proposal," the "friend" tells the magazine.

Apparently, this "friend" has no fear of jeopardizing their invite to the wedding, should it take place.

In a further display of confidence in the report, Us Weekly editor-in-chief Janice Min even appeared on Wednesday's Today show to give her summary of how the proposal went down.

Meanwhile, though Life & Style recently reported that Aniston comforted herself with an all-girls get-together on July 24 after breaking things off with Vaughn, the weekly mag was only too happy to take a jab at its rival on Wednesday.

"Back in June, Life & Style exclusively had all the details of the romantic proposal, the expensive ring and Jen's reaction!" read a post on the magazine's Website.

"So why is Us Weekly playing catch-up? Because back then, they erroneously reported that the couple wasn't engaged and now they have to admit that Life & Style was right along."

To break it down: Life & Style reports engagement, Us Weekly denies engagement, Life & Style reports breakup, Us Weekly counters with engagement report, Life & Style conveniently forgets prior breakup report, points finger at Us Weekly and says, "Nana nana boo-boo." Yes, our heads hurt too.

When it comes to their relationship, the couple have consistently played it coy in interviews. Aniston has called Vaughn "a really good, loyal friend," while he has described her as "really smart and funny and easy to be with."

Neither has gone so far as to give any hint of what the future may hold for them as a couple.

Aniston's divorce from Pitt was finalized in October 2005. While her ex's post-split activities have been well chronicled, she has taken an undoubtedly less incendiary path.

Despite attempts to keep their relationship under the radar, Vaughn and Aniston have been the subject of rampant speculation since the appearance of the first photos of them looking cozy together.

Aniston has repeatedly denied rumors that Winfrey was planning to throw an $8 million wedding in the couple's honor.

"The rumors are so unbelievable," Aniston told Winfrey in April. "For us, I guess, at a certain point, you have no other choice but to think it's funny."
