As we previously reported, Corden was forced to interrupt the 23-year old star's speech due to the live show "over-running" - resulting in Adele flipping her middle finger as she abruptly left the stage to make way forBlur's closing performance.
Speaking to BBC Radio 5Live, the Gavin & Stacey funnyman said: "I was furious and put in a horrible position. I went straight to Adele's dressing room and she was fine with me, but really upset.
"She had a speech and had a list of people she wanted to thank. The truth is, just after Adele said, 'Thank you' people were saying, 'You have to go in now'.
"I said, 'I can't. How can you cut her off'? The whole room was on its feet and they said, 'You've got to do it now'.
"And then essentially it was just such a surreal moment and everything you can hear in your ear is about five people having an argument and there's one overriding voice saying, 'James, you have to'."
People later ranted that Blur'sDamon Albarn was allowed to ramble on for over 3 minutes when it came to their acceptance speech for the Outstanding Contribution To Music gong, as James added: "I was so upset and can understand why Adele was. I didn't even watch Blur, one of my favourite bands.
"I explained to Adele that if I had my way we'd push the news for a minute and half. If it was up to me or the executive producer, that would have happened, but we can't make that call.
"It would have been a wonderful TV moment for Adele to have her real moment in the sun and then Blur come on. It's a shame we're even talking about it, but it's a live show and what can you do?
"All you can do is learn from it and the channel will learn from it and we can see how we can rectify that and change it next year. I don't think it's quite as big a news story as some might [think]. If you listen to it, it's not a bad speech. It's just unfortunate that it was cut short."
Adele has since clarified that her obscene gesture was not aimed at James or the crowd, stating: "I got cut off during my speech for Best Album and I flung the middle finger.
"But that finger was to the suits at the Brit Awards, not my fans. I was about to thank the British public for their support and they cut me off. I'm sorry if I offended anyone but the suits offended me, so thank you very much for all of your support."
The Brit Awards and ITV have since issued an apology to Adele, saying in a statement: "Unfortunately the programme was over-running and we had to move on. We send our deepest apologies to Adele that her big moment was cut short."
Previous Brit Award winner Lily Allenhas since hit out at the decision to end Adele's speech prematurely, branding it as a 'metaphor of sexism in the music industry.'
Angry Allen tweeted: "I'd rather hear Adele's acceptance speech. I can't say I'm surprised. It was like the music industry's attitude to women played out as a metaphor."
In other Adele news, the Rolling In The Deep hitmaker has managed to smash the late Whitney Houston's US chart record.

She now has the longest-running No.1 album from a female artist in the US, eclipsing Houston's achievement on 20 weeks with The Bodyguard soundtrack.
