Actress Julianne Hough is still devastated after sparking a storm of controversy over the weekend by dressing up as inmate character Crazy Eyes from TV show Orange Is The New Black for a Halloween costume party, according to her dancer brother. The Rock of Ages star has already issued a grovelling apology after stepping out wearing offensive 'blackface' make-up to the bash on Friday (25Oct13), but her brother Derek insists she's still "beside herself" for stepping out with the ill-advised look. Critics slammed Hough for her appearance and some even accused her of racism, prompting Hough to take to Twitter in an attempt to explain herself, writing, "I am a huge fan of the show Orange Is The New Black, actress Uzo Aduba, and the character she has created. It certainly was never my intention to be disrespectful or demeaning to anyone in any way. I realize my costume hurt and offended people and I truly apologize." And she's still struggling with her costume choice. Brother Derek, who is a regular on TV show Dancing With the Stars, says, "It wasn't the brightest moment in her life and hopefully it's a blip. "She didn't mean anything by it... She's my sweet little sister, breaks my heart... She is so unbelievably sorry and so apologetic. "She is just beside herself... Lesson learned."
