Duff and her boyfriend, trainer Jason Walsh, donned the costumes for the annual Casamigos Halloween party in Los Angeles Friday evening. By Sunday, both of them had taken to social media to apologize for not being thoughtful with their outfit choices.
“I am SO sorry to people I offended with my costume,” Duff wrote in tweet on Sunday. “It was not properly thought through and I am truly, from the bottom of my [heart emoji] sorry.”
Walsh also wrote in an Instagram post, "I meant no disrespect. I only have admiration for the indigenous people of America."
