Jesus Luz has doubts about his relationship with Madonna.

The 22-year-old model - who has been dating the 'Hung Up' singer since late last year - is unsure about his feelings for his "friend" Madonna and has no plans to propose to her.

He said in an interview on Brazilian TV: "Madonna is a friend who has entered my life. I don't have plans of marrying her. I can't say if she is the girl of my life."

He said: "She is a marvellous, nice person whom you not detect defects."

Jesus' father Luis Heitor Pinto da Luz recently revealed the couple are planning to celebrate their union with a Kabbalah ceremony.

However, the service - which will be conducted under the mystical Jewish faith followed by Madonna - will not be legally binding.

Luis said: "The Kabbalah ceremony in New York that will link up my son Jesus Luz and Madonna only confirms that he is extremely happy.

"I don't know if there will, in fact, be a real marriage between Madonna and my son. It will be a type of ritual, but I do not know Kabbalah or if the ceremony will have legal validity."

Luis also confirmed the couple are living together in New York with Madonna's three children, Lourdes, 12, Rocco, eight and three-year-old David.
