Fans couldn’t help but notice that Kim Kardashian’s birthday wish for Caitlyn Jenner wasn’t as warm on Tuesday.

The star of the “Kardashians” took Instagram where he commemorated the former Olympic athlete’s big day with a single image that shows the couple together and which he accompanied with a brief caption.

“Happy 75th birthday. I love you,” the Skims founder wrote alongside the photo.

Jenner responded to the post, telling Kardashian, “I love you so much. Thank you for everything”.

However, some of her fans were quick to point out that Kardashian’s message didn’t seem to convey the typical warmth she normally uses in some of her other birthday posts.

“Short and concise title with exactly one image: I’m dying,” wrote one social media user.

Another added: “It seems very forced. “Kimmy, honey, we know you didn’t want to make this post.”

“The title seems exhausted,” someone else stated, and another added: “It’s not the ‘here’s your damn post’ post.”

Another Instagram user commented: “Haha you can say you only did it because you had to what happened to the essay your whole family wrote .”

Kardashian’s birthday post for Jenner comes several months after she responded to Jenner’s claim that she was “calculated” in the documentary series “House of Kardashian,” which aired in November 2023.

The mother of four revealed Jenner’s “honestly, it doesn’t (bother me)” comments at the season five premiere of her family’s Hulu series in May.

“I had a wonderful stepfather who raised me,” he added.

“So none of those things that are said, even if they’re twisted or whatever, are going to make me think any differently about the life I’ve had.”
