50 Cent's baby mama Shaniqua Tompkins is claiming that the rapper hasn't seen his 17-year-old son in quite some time, adding that Marquise didn't know he had a new little brother until it was revealed to the media. Shaniqua told TMZ that the last time 50 Cent had seen Marquise was in May 2012, just a few months before his new son Sire was born.

50 later hit back, telling the baby mama to "Go ahead tell her I said get a job, go do something with her self. SMSaudio."

Now 50 is back at it, slamming the baby mama yet again. A source for Rumor Fix is saying that 
Shaniqua Tompkins is motivated by greed and selfishness. "Shaniqua clearly doesn't have her son's best interest in mind to drag lies into the media, her main focus is always how anything will affect her son's potential inheritance."

The sources goes on to explain to Rumor Fix that 50 provides a very nice life for her and Marquise. "She is a very well taken care of woman and so is her son — she hasn't had to work since 2002 when 50 first made it on the music scene. She has yet to have a job since then."

Rumor Fix also spoke with a rep for 50 Cent, who tells us, "50 is saddened by the attention-seeking tactics of his son's mother. He remains a proud and supportive father and feels blessed to have two sons."
