Fashion icon Calvin Klein, 83, has recently become the subject of concern among insiders and observers following a rare public sighting where he appeared noticeably frail and pale. The designer, who founded his eponymous brand in 1968, was photographed looking gaunt during a recent outing in New York City, sparking widespread worry about his health.

Sources close to the designer have revealed a concerning new obsession with thinness, with one insider noting that while he appears frail, he continues to work out daily. "He is just super thin, which he is fine with," the fashion insider told the Daily Mail. Despite his public image, Klein reportedly maintains a youthful lifestyle, with one source stating, "Klein, 83, ‘is stubborn and refuses to stay home like an old man.'"

His personal life also remains a topic of discussion, with his 37-year-old model boyfriend, Kevin Baker, reportedly playing a role in maintaining his active image. The couple has been together since 2016. However, their relationship dynamics have reportedly shifted. "According to our insider the relationship has transitioned from one of romance to companionship: 'They are just friends at this point. It’s more of a relationship for image and comfort,'" the publication reported. Klein's romantic history also includes a marriage to Kelly Rector from 1986 to 2006, and Jayne Centre from 1964 to 1974, with whom he has a daughter, Marci Klein.

Klein continues to stay connected with his social circle, often seen with A-list friends such as Christy Turlington and Kate Moss, which contributes to his continued presence in the public eye. The designer has previously expressed his views on mortality, reportedly stating an age at which he would be content to die, although the specific age was not disclosed.
