Mariah Carey Tweets Picture Of Lovely Twins !

Mariah Carey's precious twin babies undoubtedly are growing up fast.

The proud mom of nine-month old son Moroccan and daughter Monroe recently tweeted a new picture of her bundles of joy.

In a move to remind Twitterverse of her beautiful offspring, the picture was posted on the same day that Beyoncé unveiled the first image of her month-old daughter Blue Ivy. Coincidence?

"New #DemBabies picture @ http://www.dembabies.com, first one from 2012 : ) LYM!!" Mariah wrote.

The image shows the smiling siblings, who were born on April 30 last year, on a bed wearing white baby grows and looking as if they are starting to crawl.
