50 Cent ‘in tirade at teenage son’

50 Cent reportedly told his son he wanted "nothing to do" with him in an angry text message tirade.

The rapper was recently charged with assaulting the unnamed mother of one of his children.

He has now been accused of threatening to cut all ties with his 16-year-old son Marquise.

RadarOnline reports that in January, 50 Cent – real name Curtis Jackson III – sent Marquise a series of irate text messages.

He reportedly said in one text, "I don't have a son anymore" and ordered the boy to delete his number. During the heated exchange which lasted for more than an hour, he also allegedly asked the teenager to take a DNA test to prove he is his biological child after insinuating his mother Shaniqua Tompkins had been unfaithful during their relationship.

"Tell your mother she won. She has you and ill make another. I will have nothing to do with you. Don't text me ever again (sic)," the rapper reportedly fumed.

The website reports that the angry tirade began after Marquise failed to open the door to his father.

"Good luck with you life man. I tried to come talk to you. You din't have to have me come all the way out there if you don't to see me you little a*shole (sic)," 50 Cent apparently wrote.

During the conversation, the teenager reportedly suggested the music star hadn't contacted him on his birthday or at Christmas.

"F**k you all you want is a gift," the rapper allegedly responded. "Like your mother and your ungrateful sister."

Marquise apparently denied he was only interested in his superstar dad's fame and fortune.

"Well if u feel that way, I don't care about no gift it's the thought that means the most, remember this money ain't everything (sic)," read one message.

Radar claims to have verified that the texts came from a cell phone registered to G Unit Touring, the record label owned by 50 Cent.

He has not yet commented on the allegations.

50 Cent has been feuding with Shaniqua over custody and other legal issues since 2007. The rift reportedly deepened earlier this year when he filed legal papers ordering Shaniqua not to appear on US reality show Starter Wives.

The rapper currently faces up to five years in jail for domestic violence and vandalism charges after a recent argument with a woman who he has a baby with. The unnamed victim claims she had to lock herself in a bedroom after he began destroying her property on June 23. She also alleges 50 Cent kicked open the bedroom door, injuring her in the process.

His arraignment has been set for July 22.
