Comedian Dane Cook is in hot water after he refused to have his routine streamed live for the Boston Marathon bombing fundraiser because it was new material.

Thursday’s "Boston Strong: An Evening of Support and Celebration" at the TD Gardens was a star-studded affair to raise money for the victims of the bombs that rocked the Boston Marathon in April.

Singer-actor Donnie Wahlberg, Rock and Roll Hall of Famer James Taylor, Jimmy Buffett, and Cook were among the celebrities who lent their talents to the fundraising efforts, reported E! News.

Wahlberg ironically said, “To say everyone is checking their ego at the door is a cliché, but it’s true. To walk down the hallway and bump into Carole King and have her say ‘Thank you. Your city is so great…’ There’s no place for rock star attitudes tonight.”

But it turns out that Cook had that exact attitude when it came to his part of the event.

Cook performed brand new material at the benefit, but his comedy routine was not televised because he wasn’t ready for the public to hear it just yet.

The comedian explained via Twitter, “Hey everyone sorry my set was not a part of the live stream or televised! I didn't want any of the new material to hit the airwaves yet!”

This explanation only riled the event's viewers.

The sports writer for the Boston Herald tweeted: “I wish I could have used my voice to help the Marathon victims like @DaneCook. Instead, the washed-up comic uses it to kick his new career.”

Another called the comedian a “jackass” while others shared the sentiment that he should “rot in hell ASAP.”

According to Us Magazine, a representative of Live Nation defended Cook by saying, “Dane donated both his time and incredible talent to yesterday's event and was most certainly an integral part of making the evening an extraordinary success benefiting The One Fund.”

Cook stands behind is decision to postpone his routine.

He tweeted: “I can’t wait to share it soon! The event was so meaningful and special. One of the best nights of my life. #BostonStrong.”
