He calls himself "a f------ redneck," and threatens, on his MySpace page, "Ya f--- with me I'll kick ass."
This razor-tempered 18-year-old has become the centre of buzz at the Republican National Convention in St. Paul, Minn.
Why?
He is the father of Bristol Palin's unborn baby and Bristol, 17, is the eldest daughter of Republican vice-presidential candidate, Governor Sarah Palin of Alaska.
Revelations about Bristol's hockey-playing paramour, Levi Johnston, came to light in reports from the New York Daily News and the New York Post which logged on to Johnston's MySpace site.
On his MySpace page, according to the Post, he says he has a girlfriend but adds that "I don't want kids."
Still, the hockey player with the Wasilla Warriors in Alaska reportedly made no secret of the pregnancy in his hometown.
On the page he also says: "But I live to play hockey. I like to go camping and hang out with the boys, do some fishing, shoot some s--- and just chillin' I guess' "
Johnston also has been in trouble with the law, for taking king salmon from a lake out of season, according to the paper.
And he's going to have to rent a tux soon. Sarah Palin has announced that Bristol, five months pregnant, and Johnston are going to be married.
In a statement issued Monday, Palin said she and her husband, Todd, are "proud of Bristol's decision to have her baby and even prouder to become grandparents. As Bristol faces the responsibilities of adulthood, she knows she has our unconditional love and support."
The statement noted Bristol and Johnston will marry, and asked the media to "respect our daughter and Levi's privacy as has always been the tradition of children of candidates."
