The pair welcomed their twins into the world on 30.04.11 and, following days of speculation, have finally confirmed the monikers of their daughter and son. According to Mariah`s spokesperson, Monroe - who is named after late actress Marilyn Monroe, one of the singer`s biggest inspirations - does not have a middle name because her mother doesn`t have one. Her brother shares his middle name with his father, as well as it being his grandmother`s maiden name. The top tier of the 42-year-old singer`s New York apartment is called the Moroccan Room - because of its African-inspired décor - and is the place where Nick proposed to her. Mariah`s spokesperson Cindi Berger said: "It has been a long, emotional journey for this family, and I couldn`t be happier for all of them." Earlier this week, the `We Belong Together` hitmaker teased fans by revealing the twins` names both began with the letter M and invited her twitter followers to guess at what they have been called. She tweeted: "I wish I could personally thank all those around the world who continue 2 send congrats+prayers for #dembabies! they`re doing great (sic)." "And they are the most incredible gifts we could ever have imagined (sic)!" "So we r bout 2 reveal the actual names and b4 we tell em 2 our friends etc. both begin w/M`s (sic)!!!!
