Jen and Vince....engaged or not?

Us Weekly is sticking to their cover story that Jennifer Aniston is engaged to Vince Vaughn.

Aniston's spokesman Stephen Huvane attacked Us Weekly editor Janice Min after she appeared on Today, insisting the couple have been engaged for almost two months. Huvane said, "She is wrong. There is no engagement."

The executive editor of US, Ken Baker said, "You're only as good as your sources and I would just ask him to check his sources. They are engaged, they are getting married and they are as happy as they've ever been."

Us claims Vince gave Aniston a $500,000 engagement ring on June 27 after spending a vacation in Mexico together.
