Rapper 50 cent, whose real is Curtis Jackson, is still aiming for the "worst daddy of all time" title as he announced today that he re-wrote his will after a nasty showdown between him and his son.

In the text messages that were sold to RadarOnline on Monday, Jackson was "allegedly" going back and forth with son Marquise Jackson after MJ failed to open the door during a custody visit. The rapper later disowned his son and demanded a DNA test from his son's mother.

50 now believes that his 16 year-old son wasn't the one doing the texting but it was actually his son's mother Shanquia acting like him. Here's what he had to say via Twitter:

"I rewrote my will today now when I pass away all my physical property's and MOST of my money go's to charities and TIFFANY LIGHTY so when I'm done she can be 50cent #SMSAUDIO 

And that was his mother texting me as him. she sold that to a web site. she hate me for Winning, it's hard to replace me!"

Marquise then replied to his father's tweet with:
He also retweeted a Oprah Winfrey tweet saying, “I believe Fathers not showing up for their sons has left a hole in the soul of our country,” and Aubrey O’Day who posted, “Having a child doesn’t make you a father. Having the courage to raise one does!”
