The party's over for Harry Hamlin and Lisa Rinna, who took to Instagram on Monday morning to apologize for a swastika T-shirt that Hamlin wore as part of his Halloween costume.

Hamlin, 64, and Rinna, 52, attended Casamigos tequila party on Friday night wearing a couples costume inspired by a 1978 photo of Sex Pistols bassist and punk rock icon Sid Vicious and his girlfriend Nancy Spungen.

After an uproar arose this weekend over the shirt's anti-Semitic imagery, Rinna issued a joint mea culpa on social media: "If I hurt you we were being authentic to the characters of Sid and Nancy for our Halloween costumes. It hurt and angered many of you and we are deeply sorry for that. That was never our intention. We did not mean to offend. With love, Lisa and Harry."

Hamlin has not yet personally addressed accusations that his costume was "ignorant" and "offensive," and Rinna's feed still shows a regrammed group photo posted by her Real Housewives of Beverly Hills costar Kyle Richards in which Hamlin is wearing the shirt, but his jacket is zipped up to obscure the swastika.
