"Here we go again!!! We’re feeling incredibly blessed to be growing our family and this gift truly couldn't have come at a better time," the 90210 alum captioned the post. In the first pic she unbuttoned her jeans and shirt to reveal a baby bump, and in the second she held her daughter, Bowie.
"We've just settled into our new house and it really feels like home now. Bowie is absolutely itching for a little sibling to play with and look out for," she added.
"And as for @joshbeech and I, we are teammates in this life and we've shown ourselves how incredibly strong and capable we are after tackling our recent cross-country move... in a car... with a toddler and a dog... during a pandemic. So bring it on, Baby Beech #2! We're ready for ya!!!
"Thanks to those sending well wishes + congrats," the 31-year-old concluded.
Fans and famous pals rushed to the comments to congratulate the mom.
"Congratulations babeeee," Vanessa Hudgens commented.
"Congrats mama!!!!" Tori Spelling gushed.
"OHHHHHHH S***!!!!! CONGRATS SIS!!!!!!" 90201 costar Tristan Wilds wrote.
"So happy for you!" a fan told the actress.
Beech shared a photo Bowie kissing his wife’s baby bump on his Instagram account, captioning it with heart emojis followed by another close-up shot of Grimes' tummy and a pic of the mom holding her daughter's hands.
Grimes and Beech tied the knot in 2013 and welcomed their first child in 2018.
"We were blessed with a bigger and better gift than we could’ve ever imagined this Christmas, a new addition to our family!!! We found out I was pregnant two days before our first ever Christmas on our own. Unable to be with any family due to COVID travel restrictions, we were feeling pretty low about the holidays until this news came out of nowhere and lifted our spirits right up!" Grimes shared on her blog The Damn Thing.
"As with Bowie, this pregnancy wasn’t planned but I truly couldn’t have scheduled better timing for us to grow our little family. We’re ready.
"It feels like the stars really aligned to complete our family… for now. We’ll see what the future holds!"
The brunette beauty spilled in a YouTube video that they know the sex of the baby but won’t reveal it until later. Grimes explained that she was supposed to receive two emails, one with the chromosome results and the other with the sex, but both results were included in the same message. "I was just scanning through the email and I found out the gender," she said.
