Reality TV star Tila Tequila has announced her engagement to socialite girlfriend Casey Johnson in a bizarre online video.

The internet pin-up, real name Tila Nguyen, appeared with the Johnson & Johnson heiress on Wednesday morning in a video posting on Ustream.com.

Clad in black and kissing Johnson, Tequila told fans: "We have an announcement... This is exclusive and going to be all over the news tomorrow, but because I love you guys so much, we are giving you the exclusive first - Tila army fans - tonight, my girlfriend has asked me to marry her!"

The 27-year-old then flashed a what she called a "17-carat diamond ring from my baby," and hit back at rumors the sparkler is a fake, adding, "my baby is a f---king baller. She's a billionaire! She's the heiress of Johnson and Johnson."

The A Shot at Love star, who says she is "very happy" also confessed the couple are in a hurry to be wife and wife, explaining, "We're what you call U-Haul lesbians, where you meet and fall in love and move in the next day and have kids."

Tequila made headlines in September after alleging that her ex-boyfriend, football star Shawne Merriman, choked and unlawfully restrained her at his home. San Diego County District Attorney later dismissed her claims due to insufficient evidence.
