Mariah Carey is in true mummy mode as she uploads cute pictures of her one-year-old twins Moroccan and Monroe.

The 42-year-old first tweeted a picture of her and son Moroccan, who she's given the adorable nickname 'Roc Starr'.

The little guy looked straight at the camera while his mum pretended to be asleep. Aww.

It seems as though one half of the baby duo wasn't enough for some of Mariah's seven million plus followers, who asked the star to share a pic of her and baby girl Monroe.

Mariah chose a pic of her and her little girl relaxing in the pool - the singer looking gorge in a big sunhat, and Monroe playing in an inflatable car.

Broody much? Thought so.

The Hero singer was taking a much needed rest from her busy schedule - she has been promoting her new single Triumphant and recently landed a gig on American Idol.

The singer will be replacing Jennifer Lopez on the Idol judging panel and J-Lo has already given Mariah her seal of approval.

It isn't the only thing the two singers have in common - J-Lo also has twins, 4-year-old Max and Emme.

"As a singer, songwriter and producer, it’s going to be fun and rewarding to help find new talent and give back with American Idol," Mariah said in a statement issued by Fox. "I can’t wait to channel my creative energy as a part of this show which is a massive global phenomenon."
