Bristol Palin's baby daddy Levi Johnston to be a dad again

Whoa, baby.

Levi Johnston - the rough-talking, Playgirl-posing baby daddy of ex-girlfriend Bristol Palin's little boy - is about to become the father of yet another girlfriend's child.

A rep for Johnston, 21, confirmed the news to Us Weekly Tuesday.

This time around, Johnston is involved with 20-year-old teacher, and fellow Alaskan, Sunny Oglesby, who - according to TMZ.com - is about three months along and isn't yet showing.

Johnston first made baby-daddy headlines in 2008, when he and Bristol - the daughter of right-wing former vice-presidential candidate Sarah Palin - had a son named Tripp. At the time, Johnston and Bristol were both 18 years old.

According to TMZ, Johnston hasn't yet told Bristol about his second foray into fatherhood.
