Bristol Palin filed documents in an Alaskan court yesterday, demanding $1,750 per month in child support from her ex-boyfriend, Levi Johnston.

According to the papers, Levi made an estimate of more than $105,000 from media appearances and modeling gigs last year, but only paid a total of $4,400 to help with his son Tripp’s expenses.

When asked about the filing, Levi’s manager Tank Jones denied the claim, and insisted that Levi had actually paid Bristol more than $10,000 in support last year. He could not say how much money Levi actually made, but added that he was not paid for every interview that he did.
