A Bear Grylls and his rarely seen son Marmaduke has resurfaced as the 18-year-old dwarfed the adventurer, 50.
The image came a couple of days after a picture of Gary Barlow and his son Daniel went viral after the Take That singer shared a family snap of his son towering over him.
In April, Bear took to Instagram to wish his middle son - who is 6ft 4" a happy birthday with two snaps alongside his wife of 24 years Shara Cannings Knight.
Bear, who also has sons Jesse, 21, and Huckleberry, 15, with Shara, captioned the post: '18 today! We love you so much Marmaduke… keep shining bright! ❤️.'
But fans were quick to point out Marmaduke's incredible height - as in both snaps he was seen towering over his parents.

It comes days after Gary Barlow and his son Daniel went viral after the Take That singer shared a sweet family snap of his 24-year-old son towering over him
The first picture showed Marmaduke wearing his smart Eton uniform with his hair shaved into a buzz cut.
In the second snap, Marmaduke matched his father, who stands at 5ft9, in a shirt and vest combo.
Fans rushed to the comments to point out the huge height different between Bear and his son.
They wrote: 'Bear Junior is turning out to be a Grizzly'
'I think drinking p*** somehow created a super human.'
'Bear Grylls son actually a bear'; 'You must look up to him a lot'.
'What are you feeding him?!'; 'Absolute unit get him on that rugby pitch.'
'I think your son is the real bear here. Damn so tall.'
'Oh wow he's so tall. Happy 18th to him'; 'Is he standing on something? Happy Birthday Marmaduke.'
The Geordie Hiker Garrin French said: 'What you been feeding hike. 18 and already looks incredibly strong.'
Meanwhile, skier JT Holmes added: 'Definitely outgrew that windbreaker I gave him.'

In one of the pictures shared on his 17th birthday, Marmaduke appeared just a little bit taller than his mother (pictured), proving he went through a huge growth spurt in the last year
The snaps hugely differed from ones shared a year earlier for Marmaduke's 17th birthday.
In one of the snaps shared for his 17th birthday, Marmaduke appeared just a little bit taller than his mother, showing he went through a huge growth spurt in the past year.
It comes after Gary and his son went viral after he shared a family photo showing his oldest child Daniel towering over him, but many were shocked by his real height.
Gary, 53, shares Daniel, 24, Emily, 22 and Daisy, 15, with his wife of 25 years Dawn Andrews.
He tends to keep his personal life out of the spotlight, but the family photo posted on Instagram recently went viral online as a light-hearted tweet featuring it was viewed more than six million times.
Gary barely reaches his son's shoulder in the wholesome photo, which Gary originally posted to mark Father's Day in June 2023.
Memes have flooded the internet with jokes about Daniel's height.
But in reality, the 24-year-old is only a few inches taller than the average British man.
The average height for a man in the UK is 5'9, and 5'3 for a woman.
Daniel, who is pursuing a career in medicine, comes in at an impressive 6'2, but seems taller next to his 'short king' father.
But in reality, Gary is only a few inches shorter than average at 5'7.

The father-and-son duo had their arms around each other in the picture, posted shortly after Gary celebrated his son's achievement completing the Ironman competition, which saw him tackle a 2.4 mile swim, 112 mile bike ride, and 26.2 mile run.
He wrote: 'We just couldn't be prouder of our boy - unbelievable amounts of training and determination - when you put in the work you get the results. Congratulations #ironman.'
But the photo went viral, with many commenting 'Gary Barhigh' below.
Memes compared the picture to a scene in the Christmas movie Elf, where human-sized Buddy struggles to fit in at the North Pole because everything is too tiny for him.
Another captioned 'Gary Barlow's son looking at all these memes about him on Twitter' above a picture of a tiny model of a phone.
It was held in a hand which looks huge in comparison.
Another read: 'Gary Barlow asking his son for a cuddle before bed', showing the Take That star on stage with his arms spread wide above him.
Others posted photos of the celebrity with items which could be seen as clothing - such as a check pattern wall - captioned: 'Gary Barlow standing in front of his son's new cardigan.'
References were also made to how Donald Trump's son Barron - who is 18-years-old - also towers over him at an impressive height of 6'9.
The teenager was seen towering over his family as he celebrated his father's sensational return to the White House.
Donald - who is one of the tallest presidents in history - was dwarfed at Barron's side measuring just 6-foot-3, while Melania stands at 5ft 11.

Back in 2022, Gary shared another rare snap of his towering son for his 22nd birthday.
He wrote: 'Happy 22nd Birthday to our Dan. We love you mate and you make us so proud every day'.
He has his arm around Daniel's waist, with his head barely above his shoulder.
Gary previously spoke about how his children are so different to him and have shown no interest in showbiz, opting instead for academic careers.
He told The Mirror: 'The two oldest ones [Daniel and Emily] have kind of gone into medicine and physiology - studying strength and conditioning - and my youngest one, Daisy, I'm not too sure what she's heading for but again, she's very studious… unlike me and my wife.
'I don't think they will follow in my music footsteps but I wouldn't have discouraged them though if they did want to, it's been a good business for me.
'Every day I still enjoy what I do and when you realise you're making a living from it, it's a great, great place to be. Many roles in 'showbiz' are just wonderful, there's definitely a much harder world out there than the one I'm in I think'.
The Barlows sadly lost their baby Poppy in 2012 when she arrived stillborn and he recently admitted that he 'hadn't found peace' with it yet.
Speaking on The Imperfects podcast, the singer spoke candidly about his family tragedy as he explained: 'I don't talk about this in great detail and I literally don't because I'm still kind of figuring it out a little bit.
'My wife's emotions were completely different to mine. I've been angry for a long time about that, I haven't really found peace with it yet.'
