Johnson & Johnson heiress Casey Johnson, who died suddenly last week, will be buried in New Jersey on Sunday, according to Perez Hilton.

Paris and Nicky Hilton are expected to be among the mourners.

Johnson allegedly became engaged to media hound Tila Tequila just weeks before her death at age 30.

The troubled heiress had bouts with drugs and suffered from diabetes.

Her family, headed by patriarch and Jets' football team owner Woody Johnson, attended a Jets and Cincinnati Bengals game Saturday, and along with coaches and team employees, wore blue bracelets to honor Casey and to represent the Juvenile Diabetes Research Foundation, according to TMZ. The organization was founded by the Johnson family and a fund has been set up in her honor since Casey died.
