Grammy Producer Responds To Trent Reznor's Post-Show 'F#@k You'

'I'm sorry he was upset,' Grammy exec producer says, after Reznor rips telecast on Twitter.

Trent Reznor had a pretty straightforward response to Grammy producers who decided to cut short his show-topping, all-star jam on Sunday night's telecast: "F--- You."

Now, one of those producers has a response for him: "I'm Sorry."

In a post-show interview with the Hollywood Reporter, Grammy executive producer Ken Ehrlich apologized for rolling the credits over Reznor's performance (which also included Dave Grohl, members of Queens of the Stone Age and Fleetwood Mac's Lindsey Buckingham), though he explained that decision wasn't made out of malice ... but, rather, necessity, as the show had gone past its allotted three-and-a-half hour run time.

"I'm sorry he was upset. I was really thrilled that we were finally getting him on the Grammys," Ehrlich said. "The final jam started with Arcade Fire a few years ago, and LL Cool J last year. I want to end on a high note. I did tell them we'd take as long as we could. The number was about five, six minutes long, and we got to him within a minute 20 [seconds] of the end. We got as close as we could possibly get."

That echoed what Recording Academy president Neil Portnow told reporters following the show, explaining that producers simply ran out of time. "We save the end slot for something that is a bit of a jam," he said. "Because you can have the energy go and then it's just a matter of the clock."

Reznor has yet to make any further comment on the matter, and neither has Ehrlich ... though he did reveal one secret about Sunday night's show: Jay Z came well prepared for the festivities, and he likes to share.

"I really don't drink, but about an hour from the end of the show, Jay keeps a little bottle of cognac underneath his seat, and takes a taste. So I came down there a couple of times during the show and he filled my cup," Ehrlich explained to HR. "By the 'In Memoriam' segment, I was feeling pretty good!"

That's nice. Try telling that to Trent.
