A family judge ordered on Friday that the jailed ex-girlfriend of Dirk Nowitzki must undergo pregnancy and DNA testing.

The Dallas Morning News reported the ordered tests on Cristal Taylor, who claims Nowitzki is the father of her unborn child.

Medical records show that Taylor is pregnant, but Associate Judge Randall Grubbs wants his own test, according to the paper.

In addition, Grubbs sealed the proceedings; attorneys told the Morning News that they could not comment.
