Are they or aren't they?
That's the question Keeping Up with the Kardashians
fans may be asking about matriarch Kris Jenner
's relationship with husband Bruce
as family members celebrate the supposedly separated pair's anniversary.
"Happy Anniversary to one of the most amazing men I know!!!!" Kris captioned an Instagram photo on Monday, showing the couple dressed to the nines in their early days. "I love you, Wow 23 years!!!!! #love #weareofficiallyvintage"
Kris, 58, and Bruce, 64, announced their split
in October – but say they had no plans to divorce. Bruce has lived in his own Malibu home since the summer.
But the two have been spotted looking cozy as ever, even returning from their Thailand vacation hand-in-hand
Kris's daughter Khloé Kardashian
, who was raised by Jenner
from the age of 5, also shared the love over social media, Instagramming a group photo from the couple's 1991 wedding.
"Happy anniversary to my mommy and my 2nd daddy!! I love you guys! 23 years and 10 kids later," she wrote.
, however, opted for a simpler tribute, posting two old pictures of the Jenners with the hashtag "#vintage".
