Zoe Ball tickled radio listeners as she joked that she had tried to block her ex Norman Cook from her memory.

The pair - who were married from 1999 to 2016 - were reunited on Ball's BBC Radio show and shared a few laughs as they reflected on the old days.

As she introduced Cook, Ball said: “I now welcome to the show somebody you may know from The Housemartins, Pizzaman, erm… Beats International?”

She then paused as she seemed to be clutching around for his DJ name Fatboy Slim, laughing: “I forgot what you were called then! Sorry!”

"And such things as our marriage!" he replied.

According to OK!, there was another funny moment as the pair were talking about Glastonbury.

Cook said he was at the festival in Somerset in 1986, and when Ball asked if he had been playing or in the crowd, the DJ apparently teased that she knew “nothing” about him.

The radio star then joked back: “I know nothing about you. I've tried to block it from my memory.”

“No I’m only kidding,” she added.

One listener tweeted that their banter was "just lovely", although another thought it was "slightly awkward".

Ball and Cook tied the knot in 1999 and have two children together – son Woody, 22, and daughter Nelly, 13.

However, in 2016 the pair announced that they had called time on the romance, explaining that they had “come to the end of our rainbow”.
