Baby-Daddy Court — Singer, author, television personality and lawyer Lauren Lake has almost done it all, but her latest endeavor is taking her back to her legal roots.

The Michigan-born Lake, who moved to northern New Jersey in the late 1990s, practiced family and entertainment law here and remains a N.J. State Bar Association member, debuted Sept. 23 as the judge in the syndicated reality show “Paternity Court,” which hears the cases of people questioning the parentage of their children (or themselves) and provides them with a DNA test.
