The actress pleaded guilty in the college admissions on May 13
The When They See Us actress, 56, who is awaiting sentencing, wore a black leather jacket and black pants as she cradled a bouquet of flowers in her arms.
It’s unclear who or what the balloons are for, but the couple’s daughter Sofia Grace, 18, will soon graduate high school.
The pair are also parents to daughter Georgia Grace, 17.
A source told PEOPLE in April that Huffman and Macy, who married in 1997, have remained united during the difficult time.
Huffman pleaded guilty on May 13 to her role in the college admissions scandal, in which she paid $15,000 to facilitate cheating on Sofia’s SAT test by having a proctor correct the teen’s answers.
Prosecutors have recommended the actress receive four months in prison and a $20,000 fine. She will be sentenced on Sept. 13.
“I am in full acceptance of my guilt, and with deep regret and shame over what I have done, I accept full responsibility for my actions and will accept the consequences that stem from those actions,” Huffman said in April upon agreeing to plead guilty.
Huffman is currently appearing in Ava DuVernay’s Netflix Central Park Five miniseries When They See Us as prosecutor Linda Fairstein.
