The father of Sarah Palin's grandson has another baby on the way - with a 20-year-old teacher, TMZ exclusively reports.
Levi Johnston was hurled into the limelight in 2008 after it emerged he was expecting a baby with then vice Presidential candidate Sarah Palin's daughter Bristol.
The pair became engaged shortly before son Tripp's birth, but ended their relationship after a number of very public feuds.
Johnston, an aspiring actor and model, who later posed for Playgirl magazine, is now in a relationship with Sunny Oglesby.
The new baby is reportedly due in around six months time.
While promoting his book, Deer In The Headlights: My Life in Sarah Palin's Crosshairs, the 21-year-old told Huffington Post in September last year he only sees his son around once a month.

He also claimed Bristol, who was 18 when she gave birth, deliberately got pregnant because she was jealous of her mother's pregnancy.
Palin gave birth to her fifth child, a son named Trig in 2008.
Johnston said: "Bristol was on birth control for a long time. She got off it soon after Trig [Sarah Palin's son] was born. I think Trig was a big motivator for her. Her mother just had a child and I think Bristol was really jealous. She was the one who was supposed to have that kid and that's when she got off of [birth control]. We weren't practicing safe sex and she ended up getting pregnant."
For her part, Bristol released her own book Not Afraid Of Life: My Journey So Far, detailing how she lost her virginity to Johnston after getting drunk on a camping trip.
