Proving just how smitten he is with his partner, the picture that he chose to upload alongside his statement shows the duo locking lips over a dinner table.

Steven's wife-to-be is Allie Silva, a professional model.

Re-posting the same image, the pretty blonde told her own followers: 'My best friend, love of my life…YES, yes yes a million times over 💍 @steven_r_mcqueen.'

It's thought that the loved-up pair have been in a relationship for over a year, with Steven making things Instagram official towards the end of 2016.

Steven and Alexandra are regularly snapped together, often while enjoying exotic trips.

In December last year, the 29-year-old American and Alexandra posed for a shot by a waterfall in Kauai, Hawaii.

Steven was named after his famous late grandfather, 60s and 70s icon Steve McQueen.

In a 2014 interview, he revealed that it was seeing his relative on-screen that made him want to pursue a career in the spotlight.

'I started watching movies my grandpa did, and I saw what an impact they made on the world,' he said in a 2014 interview.

'That's when I said, 'Hey, I want to do that too.'
