TMZ reports that Bristol Palin has filed for $1,750 a month in child support from Levi Johnston, retroactive to the birth of their son Tripp on December 27, 2008.

Miss Bris claims that Levi has earned

in excess of $105,000 in 2009 through various media interviews and modeling related activities

and has only paid her $4,300. Meanwhile, Levi’s lawyer says the sometimes model/spokesperson has paid $10,00 in child support, and besides he hasn’t been paid for every interview he’s given, so the $105,000 is ridiculous.

But um, maybe someone wants to check around and see if family members have been paid by tabloids for selling stories about the Palins…just saying.
