Kim Kardashian announced she's expecting her second baby during the Sunday, May 31 midseason finale of Keeping Up With the Kardashians — and mom Kris Jenner is beside herself with excitement!

While most of the Kardashian family have been tight-lipped in the lead up to, and aftermath of Kim and husband Kanye West's huge news, momager Jenner couldn't keep her happiness to herself, and took to Instagram soon after the show had aired to express her thoughts about the impending arrival.

Sharing one of her daughter and West's kissing photos from their wedding day photobooth, the happy grandmother wrote a very sweet caption.

"Congratulations!!!!!!!!!! Can't wait to meet your new little love bug!!!!! Sooooo happy for you guys!!!!!!!!!! #blessed #love #family #youaresobeautifulpregnant," Jenner said.

As Us Weekly reported previously, Kim's BFF Jonathan Cheban also sent well wishes to his longtime pal on Twitter after the footage aired. "Congrats Kim!!! Baby #2!!!" he wrote.

And while sister Kourtney Kardashian has yet to comment directly on Kim's news, she was feeling pensive (and possibly a bit broody!) in the hours that followed the announcement, judging by her Instagram post — a photo of the cover of a favorite book of hers, "Someday."

"Can not read this without crying," the mom-of-three wrote about the book which chronicles the life story of a baby girl from her mom's perspective. "Good night!" she added.

Can not read this without crying. Good night!

Kim's happy announcement (which appeared in scenes teasing the second half of KUWTK's season) has been much anticipated in the Kardashian/West household. The pair have shared details of their stressful quest to give daughter North West, 23 months, a baby sibling, and even broadcast footage of Kardashian's visits to a fertility doctor.
