A 'dumb mum' branded the female version of Joey Essex by her own fiancé has become an unexpected web smash after he shared a video of her being baffled by how long it would take to go 80 miles when travelling at 80 miles per hour online.

Lauren Macklin, of Hereford, asked fiancé Dave Mapp if he would prefer 'someone brainy or someone like her' while the pair were cosy on the couch watching TV.

To ensure he knew on which side of the intellectual divide she fell, Dave put the question to her: 'How long would it take to drive 80 miles at 80 miles per hour?'

Her brains were then put to the test as she was asked how long it would take to drive 80 miles at 80mph

Lauren Macklin asked fiancé Dave Mapp if he would prefer 'someone brainy or someone like her' while the pair were cosy on the couch watching TV

He whipped out his mobile phone, already convinced his 'ditzy' 25-year-old fiancé was on the cusp of delivering something worth saving.

With the device's video camera recording, Lauren is then stumped for a full seven minutes as she first tries to answer the question - and then struggles with her labourer partner's explanation. 

After being shared online, the hilarious video has since been viewed more than four million times.

In it, blonde Lauren can be heard saying 'how am I supposed to know that?', before asking: 'How long does it take to do a minute?'

'How long would it take you to travel 80 miles?'...'8 minutes'

Right, let's work this one out: Lauren's eyes dot side-to-side as she contemplates the answer to the question

The wheels are turning: Looking for help from above, the nail technician offers up two answers - eight and 80 minutes

But...wait: The mother-of-two offers up to guesses to the answer - eight minutes and 80 minutes

Her eyes darting from side-to-side, she's clearly focused on trying to find the correct answer - even though it is stated in the question.

Lauren's first guess is eight minutes, adding that she got there by dividing eight by ten.

She later gives up, insisting that she doesn't know and that the thinking is 'hurting my brain cells'. She then again concludes that it takes eight minutes to drive 80 miles.

When pressed once more for an answer, she has a stab at 80 minutes, before finally being put out of her misery.

Thankfully Lauren doesn't drive herself yet. She estimates it could be five years before she passes her theory test as she finds if 'very tricky'.

The nail technician said: 'I am who I am and Dave loves me for who I am, which is the most important thing. He says it's exciting being with me as he never knows what I'm going to say next.

'I like making him laugh but it's never on purpose. I don't think it would be funny if I tried to make him laugh.

'I have to be careful with the kids. Sometimes Ella-Rose asks me spellings on the way to school. I just tell her it's too early in the morning. But she often laughs at me and says I don't know. I have to find an excuse if she needs help with her homework and make sure Dave is around instead!'

Lauren said that the 80mph question was particularly perplexing as she does not drive. 

Lauren has been compared to reality star Joey Essex (pictured), who is known for lacking common sense

'So I was trying to figure out how quickly Dave could drive to somewhere 80 miles away,' she said.

'I came up with eight minutes, which sounded right at first but then I realised that was a bit quick. I thought it was a trick question to be honest.'

Dave, 28, said: 'I knew she wouldn't know the answer but after she asked me that question, I thought what better time to have a laugh.

'She was completely baffled by it, even after I explained it to her. But she's always like that - things that the average person knows, she simply doesn't have a clue on.

'She's the female Joey Essex - there should be a show about her, Educating Lauren Macklin. It would be a hit, I'm sure.

Lauren was recently stumped by how footballer Wayne Rooney could play for both Manchester United and England

The mother-of-two also referred to a leopard as looking 'just like a big cat, when you think about it'

'She really is one in a million, I love her just the way she is and everyone who meets her does too. I wouldn't change her for the world as she is a laugh a minute.'

The couple met five years ago under unusual circumstances.

Lauren had spotted Dave on a night out in Hereford and took a liking to him but when he wasn't out the following week decided to ask his friends for his name.

She added him on Facebook that night and proceeded to ask if she could come over. They've been together ever since and have had two-year-old George together.

Dave also looks after Ella-Rose, six, from Lauren's previous relationship.

'Whenever I need cheering up I just ask her a general knowledge question and wait for what she says', said Dave.

'You can never predict the answers that come out.'

Another innocent victim gets stumped by the 80mph question

Lauren is happy being called 'ditzy' by her friends and says she always struggled at school with most subjects, in particular maths. She got an E in her GCSE of the subject. 

Recently, she asked Dave how Wayne Rooney could get away with playing for both England and Manchester United, and while on a trip to the zoo pointed at a leopard and said she thought it 'looked just like a big cat when you think about it.'

Despite not being the brightest, Dave insists he's the fortunate one in the relationship - adding that Lauren is way out of his league.

He said: 'As you can see, she's very beautiful, so I do think I'm punching above my weight. I'm very lucky for sure.' 

And although he's outed her online for being somewhat ditzy, Lauren doesn't mind.

'I couldn't believe it when I saw the video on social media,' said Lauren. 'I have no make-up on, it's very embarrassing.

'But once I saw how much it made him and his friends laugh I soon got over it. It's nice to make people smile and I do see the funny side.'

The 80mph question has stumped a number of unsuspecting victims online, with several similar videos posted in the past showing car passengers struggling to find the answer.
