Mariah Carey tweets photo of her ADORABLE babies

Not one to be out-done by her fellow R&B divas - in this case, Beyonce -Mariah Carey hasshared anadorable photo of her babies, Monroe and Moroccan.

The We Belong Together singer must've felt a twinge of jealousy when photos of Beyonce and Jay Z's cutesome baby Blue Ivy were released on a Tumblr site earlier this weekend. Otherwise it's just a happy coincidence that she sharedthe snapof hers and Nick Cannon's babies with the world.

The photo shows the 9-month-old twins looking absolutely adorable in matching white tops. Mariah alerted fans to it via her Twitter account: "New #DemBabies picture @ http://www.dembabies.com/, first one from 2012 :) LYM!!"

Just like Jay Z and Beyonce, who trademarked Blue Ivy's name earlier this week, Mariah has been quick to get on board with the idea of making a brand for her children. She's been calling 'dem babies' for, well, their whole lives, and has a dedicated 'dems babies' website. In her defence, the website is hardly a Mothercare-style online babygro, buggy and toy shop, but is made up of a few gorgeous photos of 'dem babies' and a link to a charity fund that she set up.

Condolences

Mariah Carey also used her Twitter account to pay tribute to friend and When You Believe collaborator Whitney Houston: "Heartbroken and in tears over the shocking death of my friend, the incomparable Ms. Whitney Houston."

"My heartfelt condolences to Whitney's family and to all her millions of fans throughout the world. She will never be forgotten as one of the greatest voices to ever grace the earth."

The pair won an Oscar for Best Original Song in 1999 with When You Believe, which was recorded for animated film The Prince of Egypt.
