Beyonce, Jay Z buy portable nursery for daughter

R&B star Beyonce and husband Jay Z have reportedly splashed out on a portable nursery for their daughter Blue Ivy to stop her feeling homesick.

"Jay and Beyonce have designed it for the Mrs Carter tour so she doesn't feel unsettled. They've got toys, a cot, a table and rugs just like the ones she has at home," a source said.

The couple welcomed their daughter last year in January.
