'Who's Casey?' Kylie Jenner fans confused as they spot 'missing' family member in vintage Christmas card

LOS ANGELES, CALIFORNIA: Kylie Jenner recently shared two photos from a vintage Christmas card featuring her family, the famous Kardashian-Jenners. While the first showed the whole clan together, the second zoomed in on the card's closing message, signed from 'The Jenners and The Kardashians.'

But one mysterious name left fans scratching their heads: 'Casey.'

Kylie Jenner leaves fans wondering about 'Casey' with vintage Christmas card

The vintage photos showed matriarch Kris Jenner with her then-spouse Caitlyn Jenner before her transition, along with Kris’ older children Kourtney, Kim, Khloe and Rob Kardashian, plus younger daughters Kendall and Kylie.

But when the second image focused on the card's sign-off message, fans were puzzled by the unfamiliar name 'Casey' signed at the end along with the rest of the family.

"Who is Casey?" wondered one fan in the comments. Another user summed up the collective confusion, stating, "Everyone wondering who Casey is and what did they do to her."

Adding to the banter, a fan jokingly questioned, "Is Casey in the room with us?"

Amidst the playful remarks, the prevailing sentiment echoed in the comments: "So are we all here asking the same question? Who tf is Casey?"

One user brazenly ventured into the inquiry, writing, "Okay I will be the one who will ask the awkward question, who is Casey?"

'Casey' refers to Caitlyn Jenner's daughter Cassandra

It didn't take internet sleuths long to get to the bottom of the 'Casey' mystery. As it turns out, 'Casey' refers to Caitlyn Jenner's daughter Cassandra Marino, from her first marriage to Chrystie Scott in the 1970s. Cassandra, now 43, sometimes goes by the nickname 'Casey'—thus explaining her seeming appearance on the vintage Christmas card.

But with no sign of Cassandra in the photo itself, which appeared cropped, fans remained puzzled. They also questioned why Caitlyn’s other children from subsequent marriages—like son Burt Jenner and Brandon and Brody Jenner—weren’t even mentioned in the card’s signature.

Caitlyn Jenner's estrangement from her older children

Caitlyn shares several other children who were conspicuously absent from the card: son Burt with first wife Chrystie Scott, and Brandon and Brody Jenner from her second marriage to Linda Thompson in the 1980s. She has been estranged from many of her older children for years, as reported by Daily Mail.

In 2015, it was revealed that Caitlyn's older kids had declined to be part of her post-transition reality show, 'I Am Cait'. Her interior designer daughter Cassandra has always shunned the spotlight. As for Brandon and Brody, the latter has been candid about Caitlyn being an absent parent during his childhood.
