Video: One of Casey Johnson’s Last Public Appearances

ET has footage of the Johnson & Johnson heiress Casey Johnson with her fiancé Tila Tequila just one month prior to her death.

"I'm here to have fun," Casey told Hollywood.tv cameras. On Dec. 8 of last year, Tila and Casey attended the Famous Stars and Straps' 10-year anniversary that was being celebrated in conjunction with Snoop Dogg's 10th album, Malice N Wonderland.

The girls flashed their "17 caret" rings to photographers, while Casey exclaimed, "We just like diamonds and I just love her."
