Current MBGN, Unoaku Anyadike, wishes her 6yr old son a happy birthday

The 21 year old Most Beautiful Girl in Nigeria 2015 queen took to her instagram page to wish her son a happy birthday. The caption read; ''Happy Birthday to my Son Onate, I remember when I had you 6years ago, nothing but joy and happiness You are a star, continue to shine so bright. I love you''

She's 21 and she has a 6 year old child? Meaning she got pregnant at 14 and gave birth at 15? Or by son, she means like adopted or younger brother?
