The National Enquirer is reporting that Levi Johnston got his ex, Lanesia Garcia, pregnant and that his fiancee Bristol Palin (with whom he has a 18-month-old son, Tripp) may call of their engagement.

But, in an interview with, Garcia, 20, says: "Point blank, it's not true at all. We haven't hung out at all since 8th or 9th grade when we broke up. I don't know where people are getting this. It's not true at all. Levi is not the father of my baby."

Garcia tells Us Johnston, now 20, was her first boyfriend. "I dated him for 2 1/2 years," she says.

She's baffled how the story spread that he got her pregnant.

"I mean, it's stupid," she tells Us. "I'm nine months pregnant. If I wanted people to think that, I would have said something like that when I first found out. I would not say something like that now that I'm getting ready to have my baby. That doesn't make sense."

She tells Us she knows the baby's father, and he's "really mad" about the tabloid report. "He's upset that this whole thing is going on," says Garcia. "It's just dumb. We're supposed to be getting ready and be excited, there's no reason for this. Levi and I haven't talked or hung out in years."

Earlier this month, Johnston and Palin, 18, exclusively revealed to Us Weekly that they are engaged.

"I wanted to talk to her, but I know she won't talk to me," Garcia says of Palin. "I wanted to tell her straight-up that it's not true. If I could say anything to her, I would love to tell Bristol, that it's not true and that I'm sorry she has had to even deal with all these lies."
