Mariah Carey and Nick Cannon celebrated the first birthday of their twins Monroe and Moroccan with a lavish party in Paris last month. The whole family got dressed up for the occasion and played with their new toys. Monroe checked out her dollhouse and tinkered with the keys on her white piano (Mariah owns Marilyn Monroe’s piano), while Roc took his red Ferrari for a spin as his proud pops looked on. Check out the adorable pics below.
