Mirrors and portraits of the couple cover almost every wall of their Las Vegas home and they constantly try to improve their chiseled physiques.

The couple fork out £4,000 each month on manicures, pedicures, haircuts, tanning and gym membership and are so serious about staying in shape that they prepare every meal days in advance.

Amateur bodybuilder Buck, 27, said: 'Without a doubt we are America's best-looking couple - that's a fact - hands down.

'If there was a competition for the world's best looking couple, I would sign up right now.

'Every time I walk by a mirror, I'm looking. I'm always asking Michelle to take pictures of my physique.'

Michelle, 33, has 34D breast implants, is 5ft 7in and weighs just over ten stone, with a 26in waist and 33in hips, while Buck weighs a little over 13 stone. 

The couple met while each was supporting a friend at a bodybuilding competition in California in February 2012.

When they met, Michelle was living in Vancouver, Canada, with a son from a previous relationship, while Buck was based in Las Vegas.

The pair had a long-distance relationship for a year before deciding to get married a year later on Valentine's Day, 2013.

Buck said: 'The first thing that attracted me to Michelle was her physique. I've always been attracted to muscly women and her quads were amazing.

'She really inspired me to get into it too - I wanted to look good next to her.'

Michelle, who has been competing in the fitness category since 2011, has always been into fitness but started training competitively four years ago. 

In 2011, she entered her first competition, the Western Canadian Championship, and was astounded when she won.

She said: 'I trained myself and in the months leading up to the competition worked so hard. 

'I was terrified when I was up on the stage. I was sweating and nervous and excited. 

'But I felt amazing when they read my name out as the overall winner. It was overwhelming.'

Since then Michelle has amassed dozens of trophies and works as a personal trainer, teaching others how to get into shape.

Buck only began bodybuilding competitively in April this year but has already won shows too.

He said: 'Michelle got me into this lifestyle, but I wanted to clean up my lifestyle and to better myself anyway.

'Bodybuilding has made me into a better person. I feel great about myself, also I motivate and inspire people.

'I look great and it has brought a lot of structured discipline to my life.'

Now the couple are inundated with attention and questions from admirers when they leave the house together.

Buck said: 'When we're together people go crazy. When we're on the strip or in a grocery store people cannot stop staring at us, we're mobbed.

'It's flattering when guys look at and appreciate Michelle. They can look but they can't touch.'
