The beef between rappers 50 Cent and Rick Ross has taken another turn, as the mother of Ross’ 2-year-old son has now come under a microscope.

Documents hit the Internet last night pertaining to Tia Kemp’s rap sheet, in an apparent attempt to undermine her credibility.

According to Broward County Courthouse records, Tia Kemp was involved in a felony case two years ago.

She was charged with one count of aggravated battery with a deadly weapon, two counts of battery and three counts of child neglect/delinquency for the unnamed incident, which took place in April 2007.

Prior to the 2007 case, Kemp was in court for another felony case in 1997.

Miami-Dade County court records show the single mother received felonies for witness tampering and threats. The discovery of Kemp’s criminal record is the latest development in the ongoing war of words between Ross and 50 Cent.

The Miami-based rapper ignited talk of a dislike for 50, after he criticized 50′s legal drama with the mother of his son, Shaniqua Tomkins, on the song “Mafia Music.”

A response from 50 soon followed with “Officer Ricky (Go ‘Head, Try Me),” an attack on Ross’ previous employment as a corrections officer.

Days later, Ross alluded to the cause of the beef on Angela Yee’s Lip Service show on Shade45 XM/Sirius satellite radio show, while challenging 50 to come up with a better response in two day’s time.

The G-Unit leader obliged with an official declaration of war, a cartoon lampooning Ross and a video that featured Kemp denouncing Ross’ street image and verifying his stint as a corrections officer.

In addition, 50 Cent insults Ross in the video and refers to his mother as “the Nutty Professor,” while taking Kemp on a shopping spree.

The clip, which debuted last week on 50′s website, thisis50.com, has garnered talk among rap fans and furthered fueled the ongoing beef.

Meanwhile, a new video for Rick Ross’ single “Gang Related” hit the Internet, featuring Ross pouring out bottles of Vitaminwater.

Like 50, Ross has utilized the small screen as a vehicle with his recently released music video for “Mafia Music.”

Both rappers have voiced their views on each other on various radio shows around the country.

Fans will decide who has the better album as 50 Cent’s Before I Self-Destruct arrives in stores in March. Ross’ Deeper than Rap will follow his rival’s opus with an April release.
