Tila Tequila

So much for A Shot at Love III. Reality star Tila Tequila is engaged to Johnson & Johnson heiress Casey Johnson.

Besides tweeting the big announcement, Tequila, 28, took to her Web site to share the good news — and her new jewelry — with her fans via video. "Tonight, my beautiful girlfriend has just asked me to marry her and check out this rock," said Tequila, whose real name is Tina Nguyen.

It is unknown how long the couple have been together. Tequila was dating National Football League star Shawne Merriman as recently as early September, when she charged her then beau with battery and false imprisonment and was hospitalized following a physical altercation between the two.

Merriman publicly refuted the charges and the case was later dropped because of insufficient evidence.
