The 9-month pregnant reality star Kim Zolciak, who will deliver twins this month, hinted via Instagram that they might be boys.

The former Real Housewives of Atlanta star created a collage of her two youngest children next to each other, perhaps to give her fans an idea of what her twins might look like.

The soon-to-be-mother of six created an Instagram post of KJ Biermann and Kash Biermann when they were 6 months to also show how much they look like their father Kroy Biermann.

"KJ on the left and Kash on the right!!! They were both about 6 months in these pics! Can't wait to meet the twins!!! #theseboyslookjustlikedaddy," she captioned the photo on Nov. 15.

Zolciak and Biermann wed in November 2011 and welcomed their first son, Kroy Jagger "KJ" Biermann, on May 30, 2011. Kash was born a year later on Aug. 15, 2012. Her two daughters, Brielle and Ariana, are from a previous relationship.

She announced her current and fifth pregnancy during the season finale of Don't Be Tardy, when it aired on June 25. She took multiple home pregnancy tests and read the results from all of them at the same time. She later told E! News she is pregnant with twins, adding, "I couldn't be more excited." 

On Sunday, Zolciak also showed off her massive baby bump again on Instagram at the request of her Twitter fans.

"Sooooo with all the request I finally decided to post My baby bump today! The twins will here this month and we are soooo excited and I'm soooo over being pregnant! #countingdownthedays," she wrote.
