Poor old Robbie Williams can't recognise a cucumber from, well, any vegetable.
Wife Ayda Field spilled the beans on Loose Women saying: "The other day I pulled out a cucumber from the fridge and he asked me what it was.
"He's only had them in salads when they've been sliced for him. He's not used to seeing them in full form."
We get it. Becoming a MEGA star at the age of 15 is forever going to alter your worldview. But we're petty sure most teenagers (not just those under Jamie's Oliver's influence) can tell a cucumber from a courgette.
Ayda explained that Robbie's rapid rise to fame with Take That "stunted" his life and prevented him from developing fundamental life skills.
It seems the better man (or his PA) can order a cake.
This latest revelation shouldn't come as a surprise given we learned back in March that Rob recently visited a supermarket for the FIRST TIME EVER at the ripe old age of 42.
Ayda told fellow panellists on Loose Women: "Rob is now 42, for the first time I took him to the supermarket.
"He is like a 15-year-old boy – he's frozen in Take That time. He literally had no idea.
"He was like, 'This is amazing, they've got everything'. I was like, 'That's what you do at the supermarket'. It was a revelation to him!"
We presume Ayda is handy enough to manage their Ocado order and change the light bulbs.
But at least Rob takes a hands-on approach to being a dad.
She said: "He's good with the kids. He changes nappies, goes to Mommy And Me with me. He sings The Wheels On The Bus.
"Teddy said to him yesterday, 'Papa, if you sing again I'm gonna put you in time out!'"
Nice one Rob, keep playing to your strengths.
