Bristol Palin, who just started her own public relations firm, and whose mom has a best-selling book for which she was paid a $5 million advance, is going after her unemployed ex-boyfriend for the cash he made posing naked.

Bristol's lawyer believes her ex, Levi Johnston, made more than $105,000 last year from nude modeling, and she would like $1,750 a month in child support.

For the future, Bristol's lawyers are adamant: every time Levi pulls his dick out of his pants, she should get half.
