Walsh dressed as a Native American and Duff wore a pilgrim costume during Friday night's Casamigos Halloween Party. The couple sent out two separate apology statements on social media, E! News reports.
The Younger actress took to twitter on Sunday and wrote: “I am so sorry to people I offended with my costume. It was not properly thought through, and I am truly from the bottom of my [heart] sorry.”
