The "I Don't" singer congratulated Bey on the news that she was also going to have twins on Instagram. 

"Congrats Bey and Jay!!! I'm so happy for you both. Having twins is the most incredible experience ever! Love, Mariah and the twins," Carey commented on Beyonce's pregnancy announcement. 

Carey and Beyonce go way back. The last time, these two saw each other was during Carey's Christmas concert in New York City in December 2016. If our calculations are correct, Beyonce was probably pregnant at the time. Monroe and Moroccan can to have a little play date with Blue Ivy while hanging out backstage. 

"Backstage at Christmas time with our beautiful children. @beyonce #christmas #family #love," she captioned the photo. 

Beyonce broke the Internet when she revealed that she was pregnant with twins. In the photo, the "Formation" single debuted her baby bump while wearing a bra, underwear and green veil.
