After denying rumors that she plans to marry at Oprah Winfrey's home in Santa Barbara, Calif., Jennifer Aniston reportedly denies picking out a ring as well.

A representative for the actress has denied reports that Aniston and actor Vince Vaughn have chosen a $500,000, 9 1/2-carat, canary-diamond engagement ring for Aniston, TV Guide reports.

"They are not engaged," the representative was reported as telling the New York Daily News.
