The mother of two of T.I.'s kids has filed a lawsuit against the rapper for more child support.

According to the Associated Press, Lashon Dixon said she's having a hard time supporting her two boys, ages 7 and 8, with the $2,000 a month she currently receives.

The suit claims Dixon, 30, wants a stipend that's more in line with the rap star's current success.

T.I., 27, and Dixon reportedly have known each other since their teens and dated before the rapper attained success.

The Atlanta rapper is currently under court supervision stemming from his 2007 arrest for attempting to illegally purchases firearms. Part of Tip's agreement to lessen his jail time is to perform 1,000 hours of community service. As a result, T.I. has signed on to promote the Hip-Hop Caucus Voter Registration Drive.---Nino "Dubs" DeLuca
