Jay-Z wants a whole ''basketball team'' of children with Beyonce.

The 'BBC' rapper has 18-month-old daughter Blue Ivy with his wife Beyonce, but said he has plans to extend their brood much further.

He told US radio station HOT 97 he ''absolutely'' wants to have more kids, adding: ''God willing! Got this little basketball team going. It's all a part of the elaborate plan [...] The world would be a better place.''

Jay - real name Shawn Carter - spoke fondly of his daughter, saying both he and his wife plan to take Blue Ivy on their respective tours, which for him will start with his Legends of the Summer dates with Justin Timberlake, which begin in London on Sunday (14.07.13).

He added: ''She's well travelled. Her passport is insane. She travels well too with no fidgeting. It's what she knows.''

The 43-year-old rapper also described what the 'Part II (On the Run)' couple listen to at home, adding: ''Beyonce has 100,000 amazing songs. Just playing 'em. [We] dance to it in our socks.''

Jay-Z's twelfth studio album 'Magna Carta ... Holy Grail' was released earlier this week.
