Rapper Jay Z has named his daughter Blue Ivy as his biggest fan.

The hip-hop superstar is adamant that while the 18 month old enjoys listening to her mother Beyonce's music, she prefers songs from her father's latest album, Magna Carta Holy Grail.

The 99 Problems hitmaker tells Vanity Fair magazine, "She likes her mother's music, she watches her concerts on the computer every night. But my album came out and she loves all the songs. She plays a song and goes, 'More Daddy, more... Daddy, song'. She's my biggest fan.

"If no one bought the album, the fact she loves it gives me the greatest joy. She's genuine, she doesn't know it makes me so happy. She just wants to hear it."
