Gwyneth Paltrow`s Children Call Jay-Z `Uncle`

Coldplay frontman Chris has also heaped praised on the `99 Problems star, saying he loves him more than anyone.

Gwyneth Paltrow's children call Jay-Z "uncle".

The 'Iron Man' actress and her husband Chris Martin are friends with the rapper and his wife Beyonce Knowles, and have grown so close recently their kids - daughter Apple, four, and two-year-old son Moses - have begun to regard them as family.

A source is quoted as saying: "They are becoming really close pals with Jay-Z and Beyonce. Gwyneth's kids call him 'Uncle Jay' and she and Chris were special guests at Jay-Z's wedding."

In 2006, Gwyneth duetted with Jay-Z on a rendition of his hit 'Song Cry' at London's Royal Albert Hall. Before the show, she gushed: "I'm a Jay-Z fan. He's my best friend."

Coldplay frontman Chris has also heaped praised on the '99 Problems' star, saying he loves him more than anyone.

He said: "He is the best rapper in the world - I don't understand what the fuss is about. I won't ever love anyone as quite as much as I love Jay-Z!"
