The custody saga continues for Nas and Kelis. Now, it appears the situation has resorted to name-calling, as the singer is claiming that Nas' lawyer has been hurling insults at her legal team.

Nas and Kelis have been back in forth in court over the custody of the son Knight. In documents recently obtained by TMZ, it sounds like things are getting pretty tense. Kelis claims she recently sat in for a deposition on the matter and was shocked when Nas' attorney referred to her lawyer Navid Moshtael as a "fattie" and a "dick." The insults might lead to more issues in the case.

This custody battle has been ongoing for a while and has gotten ugly in the past. In December, news broke that Esco was attempting to spend more time with their son, but alleged Kelis would not comply with his requests. According court documents, Nas claimed the "Milkshake" singer was getting "hostile" during negotiations. He asked a judge to step in.

In February, Kelis requested Nas pay more child support. Court documents state Kelis gets $8,000 a month, but she wanted the payments increased. She reasoned Nas is doing better financially, so she should be getting a bigger check for their child.

The Life Is Good rapper reportedly recently made $40 million from an investment in the smart video doorbells company Ring, which was purchased by Amazon for $1 billion.

Nas and Kelis married in 2005 and stayed together for five years before calling it quits in May 2010.
