Calvin Klein, 83, and his model boyfriend Kevin Baker, 36, hit the gym in matching outfits after THAT awkward stumble

There may be a whopping 46-years between them, but Calvin Klein can still keep up with his longtime toy boy.

On Monday, Klein, 83, and his model boyfriend Kevin Baker, 37, were spotted leaving Gold's Gym together in Venice, Los Angeles. 

Despite Klein recently stumbling in front of his much younger beau during an awkward outing in New York last year, the sprightly designer looked much more steady on his feet for this outing. 

Showing that they share more than a love of fitness, the devoted couple flaunted their love by donning matching outfits.

They both wore sporty charcoal pants and identical long-sleeve black tops, but maintained some semblance of individuality by rocking different sneakers. 

The pair, who have been together for around a decade, are notoriously private when it comes to their relationship.

Klein rarely even gives interviews, and when he does, he sticks to topics around his career and iconic brand.

In 2003, Klein and his co-founder Barry Schwartz sold Calvin Klein Inc. to PVH Corp. in a deal worth around $700million. 

Klein pocketed $215million in the deal and remained at the company for several more years as a consulting creative director.

The famed designer has dated both men and women throughout his life. 

He was previously married to Jayne Centre Klein (1964-1974) and Kelly Rector (1986-2006). 

After his split from Rector, Klein went on to date gay male porn star Nick Gruber, who was 48 years his junior. 

They split in 2012 after two years together and Klein eventually found love with Baker.

Before meeting Klein, Baker was best known for modelling alongside his chiseled twin brother Joel, with the Baker brothers even partaking in a fully nude shoot together at one point.

Last November, Klein and Baker raised eyebrows after stepping out in 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 contacted Klein for comment at the time.
