Rap star T.I. has been sued by his former girlfriend and mother of two of his sons claiming she is in vital need of more child support payments.

According to the Associated Press, Lashon Dixon has reportedly been receiving $2,000 a month for their two children, ages 7 and 8 . Rather than demanding a specified amount, the 29 year-old is requesting a court to order a stipend equal to Tip’s financial success.

The two allegedly grew up together since they were teenagers and were romantically involved prior to his platinum-selling status in today’s hip-hop climate. In addition to Dixon’s two sons, Tip also has two boys with fiancée and R&B singer Tameka “Tiny” Cottle.

The Atlanta-bred rapper is currently fulfilling his 1,000 hours of community service for his gun possession charges last year.

T.I.’s rep was unavailable for comment at press time.

In related news, the self proclaimed “King of the South” made his first awards show appearance since being arrested at last year’s BET Hip-Hop Awards in Atlanta at MTV’s VMA’s last weekend. He gave a star-studded performance with his Billboard record-breaking smash “Whatever You Like.” Shown walking a video hottie across the Paramount Studios backlot, visiting a fur shop, a club and finally riding in a Phantom, Tip then hit the stage to debut his new single, “Live Your Life,” with Rihanna off his upcoming release Paper Trail.

Paper Trail is currently scheduled to hit stores Tuesday, September 30 on Grand Hustle/Atlantic Records.
