Tila Tequila has announced she`s pregnant.

With a baby for her brother.

Even we didn`t see this one coming - but can it be true?

The US reality TV star Tweeted yesterday: "I am going to become a SURROGATE MOTHER for my brother and his Wife!!...That is my xmas present to them," she writes. "I`m pregnant!!!"

Her announcement comes weeks after revealing her engagement to Johnson&Johnson heir Casey Johnson.

She recently showed off her engagement ring, boasting that it`s a "17-carat diamond ring from my baby... My baby takes care of me. Beat that J.Lo! Beat that Khloe and Lamar!"

Earlier on Sunday she gave a hint of the news to come, writing she was about to give her brother a present that would "CHANGE HIS LIFE AND MINE FOREVER!!!! ITS HUGE!"

And her spree of generous Christmas gifts to her loved ones doesn`t end there.

Tila added she`s "going to surprise my Mom & Dad & buy them a new house in Vietnam where they can retire & B happy."
