“So what do you do for work?” Jonathan asked.
“I go back and forth between Los Angeles and here … I do some TV presenting,” Richard explained.
“I don’t watch TV,” Jonathan said.
Speaking to the camera, Richard said: "It was refreshing, but at the same time, when someone is supposed to know who I am, and they don’t know who I am. It was awkward, it was very awkward."
Jonathan Googled Richard while he was in the toilet.
“Once he worked out who I was he loosened up and I saw a fun side to him,” Richard told the camera.

The former Today show colleagues came to blows last year when Richard revealed during his stint on I’m A Celeb that Karl had got a hair transplant.
During an interview on KIIS FM’s breakfast program alongside his Today co-host, Allison Langdon, Karl lashed out once again at his former colleague.
"When Richard mentioned [the hair plugs] on I'm a Celebrity, what were your thoughts on that, Karl?" asked radio personality Jackie 'O' Henderson.
Karl replied: "Richard and I have had a beautiful relationship over many years and, well, I'll just say this, I never really saw him in person because he was always too busy flapping about.
"And so when he said it, I had to turn off that show and I just thought, 'You are just a tosser.' Richard Reid is a tosser of the highest order!"
Speaking about Karl's comments to the same show, Richard said: "At least I'm a tosser of the highest order! Does that mean I get a crown or a medal?”
When Kyle Sandilands asked directly if Richard had a problem with his ex-colleague, he replied sarcastically: “I like Karl just fine. I like him just fine in small doses.
"I don't have a problem with Karl... not much.”
However he admitted he disliked Karl for “talking about himself in the third person” and for being “full of himself” on set of the Today show.
On last year’s I’m A Celeb, Richard stunned viewers after spilling how he discovered Karl had secretly got a hair transplant.
“So I go into the hair room, and this guy looks up and he's kind of balding... It was Karl Stefanovic without his spray-on hair!
“And then he went away and got hair plugs. He had one of those six-week vacations and came back with [makes gesture for hair plugs]. And he still used the spray-on until it filled in.”
