According to a news report, James Corden’s behavior spiraled out of control during the height of Gavin & Stacey’s popularity.

Although he is in the news again for being banned from a top New York City due to his treatment of waiting staff, Corden has previously spoken about his unacceptable treatment of other people.

At his lowest point, he confessed to being “rude” to his closest friends and colleagues, including his best pal and Gavin & Stacey co-creator Ruth Jones.

The duo met while starring on ITV drama Fat Friends in 2000 and worked together to write the script for their own sitcom.

The show’s popularity was such that the BBC requested a series, and James and Ruth soon became household names playing Smithy and Nessa, as well as writing the show.

They won several awards, including Television Programme of the Year at the 2008 TV Baftas.

During the awards ceremony, James used his acceptance speech to express his disappointment that the series had not also been nominated for Best Sitcom.

He later wrote in his 2011 autobiography that he realized the impact of his speech, saying, “Rather than using my speech to thank everyone who’d helped on the show, I’d ruined the moment and belittled myself in the process.”

James’ behavior worsened over time, to the extent that he began to be rude to Ruth.

“As 2008 wore on, it got so bad I was being rude to my agent and I even started being rude to Ruth. If I was in company and the conversation wasn’t revolving around me, I would just switch off,” he said.

Despite this, James’ career continued to grow, and he starred in comedy sketch show Horne & Corden with Gavin & Stacey actor Matthew Horne.

They also both starred in their own horror-comedy movie, Lesbian Vampire Killers.

However, both the sketch show and film were panned by critics and audiences, which led to James and Matt’s drifting apart, and they no longer spoke.

James became unhappy and admitted that he had become a different person. “We had gone from heroes to zeroes.

It hurt. I knew I was to blame. The person I had become wasn’t the person I had wanted to be.

I had drifted so far from my close friends and family that I didn’t know how to pick up the phone and talk to them anymore.”

Thankfully, James took some time out to re-evaluate his life and managed to turn things around by starring in stage play One Man, Two Guvnors.

When the play went to Broadway, he won the Tony Award for Best Actor, which led to him being cast in the 2014 film Into The Woods, before being chosen to host The Late Late Show.

James has maintained a close relationship with Ruth, who recently said that they would “always be friends” because they shared the “life-changing experience” of the hit TV show becoming a success.

She explained that “neither of our careers would be what they are if it wasn’t for Gavin & Stacey, and we’re both incredibly grateful for that.”

Despite their on-screen romantic links, Ruth is married to David Pete, while James is married to Julia Carey.

They still argue from time to time, but they feel like they are as close as family members.

Rob Brydon, who also starred in Gavin & Stacey with the pair, once opened up about the time when he confronted James about his changing behavior.

The Uncle Bryn actor said he took James out for lunch to have a word with him about his antics.

“He was burning the candle at both ends and becoming ratty and irritable,” said Rob.

James is set to return to the UK after seven years as host of The Late Late Show.

Ruth hopes to see more of her friend when he returns to the UK.

She stated that they are “friends more than writing partners” and that “it will just be really nice to see more of him. Because I haven’t seen him now for over a year.”
