Lanesia Garcia: Levi Johnston's newest Baby Mama?

bristol-pallin-levi-johnston-us-weekly,jpgDid Levi Johnston father another out-of-wedlock baby when he and Bristol Palin were on a break? Condoms, dude, condoms! Don't they have these things in Alaska?

According to Radaronline, Bristol is "heartbroken" after finding out that her recently forgiven, on-again fiance may have gotten his ex-girlfriend -- Lanesia Garcia -- pregnant.

And of course, she had to read about Lanesia's pregnancy in the National Enquirer. Ouch.

Garcia and Levi reunited briefly  during his break-up from Bristol. Levi -- of course -- insists the baby isn't his, claiming that he was one of three men with Lanesia during the week of conception.

According to friends, Bristol is devastated by the news and is thinking twice about marrying Levi. And after she already made plans to wear a white Carolina Herrera gown and have Levi and baby Tripp wear camo vests.
