Melanie Chisholm couldn't stop laughing when her brother made a dig at Victoria Beckham during an appearance on The One Show on Wednesday.
Paul O'Neill and Mel will make their Celebrity Gogglebox debut this Friday, along with various other famous faces.
While discussing the series on The One Show, the conversation soon turned to Paul spending time with Victoria's husband David while the Spice Girls were on tour.
The hosts were keen to hear about the story where Paul "saved David Beckham" and asked him about it, to which he cheekily replied: "Yeah, I saved him from his wife."
Mel, 47, instantly laughed at her brother's playful dig, as did the hosts, as Paul quickly added: "No, I'm joking - would she watch this?"
As the hosts joked they would be sure to send it to Victoria, Paul went on to recall a time he "pied off" David.
Explaining that they hung out together a lot during on particular Spice Girls tour, Paul said: "He kind of latched on a bit with us, we were like, 'David Beckham, what a guy', and so we kind of hung around with him.
"He thought my mate Rich was hilarious as he's a proper lad, so we saw quite a lot of him on that tour situation."
Paul continued: "Then I saw him on a job a few years later, and I didn't got and see him because you get busy, so I'm trying to get my guest in and I see David walking over and I was like, 'he's recognised me'.
"He's like: 'Alright Paul, how's it going?', the nicest guy, he said, 'Come on, let's get a selfie and send it to your Mel', and I was like, 'I ain't got no time!'"
Mel and the hosts laughed as Paul declared: "I pied off David Beckham!"
