Casey Johnson, heir of Johnson & Johnson empire and fiancee to Tila Tequila, has been found dead on Monday, January 4. The body was discovered in Los Angeles in the morning but the cause of death is still "undetermined".

Tequila has since tweeted about her lover's death, writing "Everyone please pray 4 my Wifey Casey Johnson. She has passed away. Thank u for all ur love and support but I will be offline to be w family." However, an hour later she updated her followers with "This is a very heartbreaking time for me. I just want some pricacy as I deal with the loss of my Fiance Casey Johnson. I'm heart is shredded."

There was a time when Tequila announced that Johnson was in coma instead of dead like many had reported. Asking for some prayer, Tequila tweeted, "I know u can feel me Casey! Dot let go! I'm almost home baby please hang on! We have a beautiful life planned out for us! I LOVE u! Hang on!".

Details on the actual incident are still blurry but Johnson is confirmed dead at 30 years old. The daughter of Woody Johnson who owns New York Jets announced her engagement to Tila Tequila at Travis Barker's clothing line party last month, showing off their diamond rings.

TMZ spoke to Tequila shortly after Johnson's death and she said they had a fight last week. Johnson turned off her phone on December 29 and was not contactable since. Tequila finally tweeted on Monday, January 4 night, "R.I.P my Angel. @caseyjonsonJnJ u will forever be in my heart! I love u so so much and we will Marry when I see U in Heaven my Wifey."
