Mathew tells British talk show host Lorraine,
''Solange, my youngest daughter has Julez, my grandson who I love, he's seven years old, he's at school and then there's Blue Ivy."
''I was with Blue Ivy two days ago, I had her in my arms and was singing a song I used to sing to Beyonce and then after I finished singing the song she kind of went, 'Ahhhh.' ''
