Reality television star Tila 'Tequila' Nguyen is likely to be interviewed by police about late socialite Casey Johnson's possible prescription drug use, according to Fox News.

The 30-year-old Johnson & Johnson heiress was found dead in her home near West Hollywood Monday morning, and Los Angeles police have opened a death investigation, although no foul play has been suspected. Officer April Harding could not confirm comments attributed to fellow Officer Sara Faden that investigators would inquire about prescription drug use, but she did say that “whatever leads” are out there will be pursued. reported that Nguyen suspects prescription drug use might be involved in Johnson's death. When asked if Nguyen would be interviewed by detectives regarding her friend's use of such medications, Faden is quoted as saying, “There were no apparent signs of foul play but the detectives will still follow all leads, each and every one, including that one.”

The heiress was reported dead about 11:51 a.m. Monday in her home at 910 N. Orlando Ave. after a maid reportedly ran screaming from the home. Nguyen, perhaps the last person to see the socialite alive, said she spent the Christmas holiday weekend with Johnson and that the heiress was incommunicado after that. TMZ reported she might have been dead for days when her body was discovered Monday.

In November Nguyen and Johnson staged an engagement live via web video. Nguyen has been no stranger to controversy — or the spotlight.
