Mariah Carey, Moroccan and Monroe
And it looks like the four year olds both have inherited their mum's tightly curled hair - too cute!
Mariah kept the 'M' naming tradition alive when naming the twins Monroe and Moroccan in April 2011.
Monroe is said to be named after film star Marilyn Monroe, while Moroccan's name was taken from the Eastern-inspired room in which Mariah's then-husband Nick Cannon proposed.
Although the couple separated in 2014, they remain close friends and are still pictured doing things with the kids as a family. In June 2015 Mariah sent a touching Father's Day tribute to Nick with pictures of the twins holding up artwork they'd drawn for him.
