Denise commented that T.R. Knight stammered a lot during his Ellen interview today. If you didn’t get to see today’s episode of Ellen, here’s what she’s talking about:

Neil Giuliano, the president of the Gay & Lesbian Alliance Against Defamation (GLAAD), has requested that Isaiah Washington apologize for the use of an anti-gay slur. As you heard in the Ellen interview, Isaiah denied using the slur while speaking with the press at the Golden Globe Awards.

“No, I did not call (co-star) T.R. (Knight) a faggot,” Washington said. “Never happened, never happened.”

Isaiah’s statement sparked anger from Grey’s Anatomy co-star Katherine Heigl:

“I’m going to be really honest right now, he needs to just not speak in public. Period,” Heigl told “Access Hollywood” at a Golden Globe after-party. “I’m sorry, that did not need to be said. I’m not OK with it.”

She called the comments “hurtful,” characterizing the incident as one that should be handled privately among the show’s cast and crew.

“I don’t think (Washington) means it the way he comes off,” Heigl said. “But T.R. is my best friend. … I will use every ounce of energy I have to take you down if you hurt his feelings.”
