While the first half of season nine of Keeping Up With the Kardashians showed Bruce and Kris Jenner co-parenting after announcing their separation, the second half could show the couple rekindling their romance.

Bruce and Kris Back Together For 'KUWTK' Cameras?

Kris took to her Instagram Monday to wish her estranged husband a happy anniversary. Considering they announced their separation after 22 years of marriage in October of last year, it's interesting that Kris still recognized the day publicly.

She shared a picture of the two back in the good old days and added the caption, "Happy Anniversary to one of the most amazing men I know!!!! I love you, Wow 23 years!!!!! #love #weareofficiallyvintage"

Kim Quitting 'KUWTK' Because of Kanye?

More than 157,000 of her followers liked the pictures, but some fans had mixed feelings about it.

One wrote, "If you weren't such a self-centered money hungry stage mom with low class daughters you'd probably still have him."

Another added, "Congrats to u both you are wonderful caring people who deserve the best."

Still, their children got in on the throwback fun too.

Khloe Kardashian posted an old school picture of the family with the caption, "Happy anniversary to my mommy and my 2nd daddy!! I love you guys! 23 years and 10 kids later."

Kim also shared a picture of the couple on the beach. She did not add a caption.

Rumors of a reconciliation between Kris and Bruce started circulating when the couple was spotted at the Los Angeles International Airport rocking wedding rings on their ring fingers.

They had just returned to the states from a family trip in Thailand.

When a photographer mentioned they should get back together, Bruce answered that they've always been together.

Find out what's really going on between Bruce and Kris when Keeping Up With the Kardashians returns from hiatus in June. In the meantime, check out Enstars for more updates and spoilers.
