Levi Johnston, 21, the man who impregnated former Alaska governor Sarah Palin's teenage daughter Bristol Palin, is going to be a dad again. Johnston's girlfriend of about a year, Sunny Oglesby, 20, is pregnant with the couple's first child, UsWeekly reports. The two love birds are not married.

Oglesby, an Oregon native who is now a school teacher in Johnston's native Wasila, Alaska, is less than three months along in her pregnancy.

Johnston previously had son Tripp, 3, with ex-fiancee Bristol. He went on to capture the nation's attention by posing nude for Playgirl, writing a tell-all book called Deer in the Headlights and briefly running for mayor of Wasila in 2011.
