Tiallondra Nicole Kemp claims Ross has not offered financial support to raise their son, two-year-old William Leonard Roberts, III.

Kemp has also asked a Florida court to order Ross to take a paternity test to prove he is the father's child. Kemp believes the results of the test will help establish her case.

Kemp requests maintenance payments under the Florida Child Support Guidelines and wants shared responsibility over the child.

But Ross' attorney Allan Zamren insists the star is a model father.

He tells TMZ.com, "(Ross) is an excellent person and an outstanding member in his community. I've known him for quite some time and it's a pleasure to represent him."
