"Everything is fine," her attorney Bob Wilson told PEOPLE on Thursday. "She's doing great."
Wilson appeared in place of Bynes's usual lawyer Richard Hutton at a Los Angeles hearing for the starlet's DUI arrest, which dates back to April 2012.
A plea in the case has still not been entered up to this point, but Wilson assured the judge one would be ready by March 3.
Following her December release from an inpatient treatment facility in California, Bynes, now a Fashion Institute of Design and Merchandising (FIDM) student, 27, recently completed a healthy week at Miracles Utah Fitness Retreat.
