50 Cent -- I Didn't Kick My Baby Mama

50 Cent is adamant ... he did NOT kick his baby mama during an explosive argument last month.

50 Cent's attorney released a statement, saying, "Curtis Jackson [50 Cent] denies these allegations as made against him. It is important to note, Mr. Jackson has not been arrested and there is no warrant outstanding for his arrest."

TMZ broke the story ... 50 was charged with domestic violence this week following the alleged domestic dispute at his baby mama's Toluca Lake home, during which he allegedly kicked her and destroyed a bunch of her property (more than $7,000 worth).

50's attorney adds, "We have been in contact with the LA City Attorney's Office and are currently conducting our own investigation into these allegations."

50 was hit with 5 charges in total stemming from the incident -- including 1 count misdemeanor domestic violence and 4 counts of misdemeanor vandalism. Cops responded to the scene following the incident, but 50 had already left.
