Nigel Lythgoe has apologized to GLAAD and his Twitter followers after making comments against a same-sex dance pair on Thursday night’s So You Think You Can Dance premiere, reports

The judge sparked outrage — including a boycott campaign from GLAAD — after he told male partners Misha Belfer and Mitchel Kibel: “I think you will probably alienate a lot of our audience. I mean, we’ve always had the guys dance together on the show, but they’ve never really done it in each other’s arms before.”

After the show, he posted on Twitter: “The same-sex ballroom guys did remind me of Blades of Glory. However, I’m not a fan of Brokeback ballroom.”

In his apology, Lythgoe said he sincerely regrets the fact that he had upset people with his poor word choices and comments.

“Professionally and personally, I believe the sexual orientation of an auditioner or contestant is irrelevant. All that said, the fact that I have unintentionally upset people is distressing to me and it is obvious I have made mistakes that I must learn from. I trust that my humour will be more sensitive and mindful moving forward,” he wrote.

He also posted on Twitter: “I wholeheartedly apologize for my Brokeback Ballroom Tweet. It was insensitive, ignorant and stupid. I have upset a number of dear friends.”
