Sexy mama-to-be!

Leah Jenner took to Instagram to show off her growing baby bump, posing for a pic in nothing but underwear and a floral night gown.

"Soooo... boy or girl?!?!?! ...or burrito??," she captioned the cute candid.

The "Keeping up with the Kardashians" star is expecting her first child with husband Brandon Jenner, and she's been sharing pregnancy photos with her fans along the way.  

The Jenner clan announced they were adding to their brood back in March.

"I can't wait to meet this little person," Leah posted on the social media site on Mother's Day. "#AlreadyFeelLikeAMama," she wrote with a family snapshot with her husband, brother-in-law Brody Jenner and mother-in-law Linda Thompson. 


Last month, Brandon shared a photo of the pair enjoying a vacation in Maui, writing, "Revisiting the spot where Leah and I got engaged eight years ago." 

We can't wait to see their little one!
