Mariah Carey's baby daughter is not yet two-month-old, but she already knows how to express "no camera, please!" with her gesture. In a picture put up recently on Twitter by the "Hero" hitmaker, baby Monroe is seen holding her hand up in front of her face and shading her eyes from the camera flash.

Along with the photo, 42-year-old Mariah wrote, "#dembabiesruntings -This is baby Monroe saying 'no pictures dahhhhling' at 7+1/2 weeks..oh dear :)." Her husband Nick Cannon has previously admitted that Monroe is already taking after her pop diva mother. To Us Weekly, he said at the time, "When my daughter wants something, she'll let you know immediately."

Before Mariah came out with the photo, her ex-husband Tommy Mottola and his current wife Thalia announced that they have welcomed a baby boy. It was Thalia who broke the news, writing on Twitter, "Thalia, Tommy and Sabrina joyfully announce the birth of Matthew Alejandro Mottola, born 6/25/11 at 11:48am weighing 7lbs 14oz."

Mariah herself gave birth to daughter Monroe and son Moroccan via C-section on her and Nick's third wedding anniversary back on April 30. A representative for the singer wrote on her Twitter page, "Congratulations to Mariah & Nick on the birth of #dembabies!! Born, April 30th at 12:07pm ET. Mommy, Daddy & #dembabies are all doing fine!"
