Tila Tequila pregnant?

Tila Tequila is full of surprises. Tequila says she plans on “giving the gift of life” for Christmas and is being a surrogate mother for her brother and his wife. Tequila posted a tweet on Sunday that let her followers know that she is pregnant.

However, the 28-year-old has made pregnancy announcements on Twitter before, and they have been false. According to CNN.com, Tequila made a Twitter announcement during the summer, saying that she was pregnant, but the tweet was quickly taken down. She then posted a blog saying: "The point is…maybe I was pregnant, or maybe I wasn't pregnant. I think that is something very personal but I'm going to clear that up now and say that I am not currently pregnant."

Tequila also plans on buying her parents a house in Vietnam for Christmas, she said, so they can retire and “be happy.”

Earlier this month, Tequila announced that she was engaged to Casey Johnson, the Johnson & Johnson heiress. Currently, Johnson’s adopted daughter, Ava, is in the custody of Johnson’s mother, Sale Johnson. Tequila and Johnson are trying to reclaim Ava from Johnson’s mother.

Sale Johnson took custody of Ava at the beginning of 2009 because she was concerned for the child’s safety.
