Paul Knightley first came under fire for planting a peck on his mother Gaynor during an episode of 'Sam Faiers: The Baby Diaries' two years ago, and he insists he will "always continue" to smooch his mother, despite facing the backlash.

He said: "I don't find anything wrong with it. I'm really close with my mum. It's just something I've always done and will always continue to do.

"I even kiss my son and my daughter on the lips, it's just something we do. I didn't find it strange."

The 29-year-old property developer and estate agent - who has kids Paul, two, and 18-month-old Rosie with Sam - faced criticism online from many viewers who deemed the intimate moment inappropriate.

Former 'Celebrity Big Brother' housemate Chloe Goodman wrote on Twitter at the time: "All that was missing was the tongue? anyone else? #babydiaries. (sic)"

Sam and Paul - who met at a restaurant in Essex in 2014 - are still sleeping in separate beds following the birth of their daughter to ensure everyone gets some shut-eye, but they are looking forward to spending some quality time together this weekend.

Paul said: "It's just sleep."

Speaking in a joint interview on 'This Morning', Sam added: "Everyone gets to sleep in our house. We're alright we still have our moments.

"This Friday it's Paul's 30th. We've got a night off from the children our first night off in like months."
