Fashion designer Calvin Klein, 83, and his much younger model boyfriend Kevin Baker, 36, raised eyebrows after stepping out last week.
The couple, who have a 46-year age gap and been together for almost a decade, hit New York's East Village to celebrate the launch of Vogue photographer Steven Klein's new book.
Unfortunately, Klein ran into some trouble while entering The Brant Foundation art gallery, where the star-studded event was being held.
The octogenarian became confused by camera flashes at the entrance, which caused him to stumble and become disoriented.
Klein muttered that he 'wasn't expecting that' as he attempted to make his way up the steps to the front door.
Seemingly unconcerned by the entire situation, his stone-faced partner Kevin simply moved away and didn't appear to give Klein a second glance before heading inside.
Meanwhile, a security guard was left to guide Klein up two steps as the designer stumbled a second time.
Daily Mail has contacted Klein for comment.
The clip drew a strong reaction online, with many social media users claiming that Kevin didn't show enough interest in helping Klein.
'Damn, he ain’t even help pops up the stairs,' wrote one, while another commented, 'He's so rude for not helping him.'
'I would imagine Calvin would hate it if his sexy young thang treated him like an invalid geriatric,' wrote another. 'Kevin is doing his job of being good looking arm candy.'
The couple have been dating since at least 2016, when they made their first official public appearance together at the American Ballet Theatre 2016 Fall Gala.
Prior to that they had been spotted together in March 2016 at the Mint Luxury Conference in Mumbai, India.
Klein was previously married to wives Jayne Centre Klein (1964-1974) and Kelly Rector (1986-2006).
Back in February, Klein made a rare appearance with ex-wife Kelly almost 20 years after they divorced.
The designer and his former wife were seen walking into his show in New York City.
'Calvin was in a great mood and though he looked frail in the photos, he was quite spry at the event, he had a ton of energy, he is in good shape, and made sure he said hello to a lot of old friends,' a source told Daily Mail at the time.
'He is still close to Kelly, they have a lovely friendship and she is happy to be by his side for his big events, it thrills her.'
From 1964 until 1974 Klein was married to textile designer Jayne Center with whom he shares a daughter, TV producer Marci Klein.
In 1986 he married his assistant Kelly Rector who he was with until they divorced in 2006.
In his heyday, he frequented the famed Studio 54 nightclub and was photographed with some of the biggest stars of the era.
These days he rarely makes public appearances and seems to be content puttering around Los Angeles with his model beau Kevin.
