Former Playgirl pin-up Levi Johnston continues to spread his peculiar brand of DNA around Alaska. In a not-so-shocking revelation, TMZ is reporting that the 21-year-old high-school dropout has knocked up yet another galpal. This time the lucky winner is Sunny Oglesby, his girlfriend of one year. The good news is that as a school teacher, the 20-year-old is good with children, which means she will be able to care properly for both Johnston and their new baby. According to sources, Oglesby is not even three months pregnant. Supposedly, Johnston has yet to spill the beans to ex-girlfriend Bristol Palin about little Tripp's impending half-brother or sister. Insiders maintain that Johnston is "so excited" about having yet another baby, especially because he believes he's been cut out of his 3-year-old son's life by Sarah and Todd Palin.
