Johnston, who's already the father to 3-year-old son Tripp with his ex Bristol Palin, is expecting another bundle of joy with his girlfriend, according to his rep.

The Alaska native's new girl, 20-year-old teacher Sunny Oglesby, currently resides in his hometown of Wasilla, Alaska.

Johnston and Oglesby went public with their relationship in December 2010.

Levi was previously engaged to Bristol in early 2010, but the two called it off in the fall after he allegedly cheated on her.
