Caitlyn Jenner Shares Adorable Photo For Khloe Kardashian's Birthday

For most of us, the hardest part about keeping up with the Kardashians is probably keeping track of all their birthdays, but that's not the case for Caitlyn Jenner.

Jenner has a lot on her plate right now, with her upcoming documentary series "I Am Cait" premiering next month -- but she still made sure to recognize daughter Khloe Kardashian's 31st b-day Saturday. Jenner shared an adorable photo with Khloe on Instagram captioned "Happy birthday, beautiful!"

Happy birthday, beautiful! @khloekardashian

And another with Kourtney and Khloe, captioned to give a nod to their absent sisters, Kim and Kendall:

Kardashian was obviously appreciative of all the well wishes she received and took to Twitter to let everyone know she was grateful:

Thank you!!! Thank you!!! Thank you!!!! It's not even midnight and I'm feeling the LOVE!!! ❤️
