Jay-Z usually isn’t one to miss out on a business opportunity, so he’s mad at himself for thinking of a seriously good one about two years too late. He admitted he wishes he’d cashed in on pop star Rihanna’s 2007 hit single “Umbrella” while it was still riding high. He said: “We really should have had some Rihanna Rocawear umbrellas when that song became a hit. We could have made a load of money on those. I’m still kicking myself.”

Jay-Z (who owns Rocawear) thinks the signature umbrellas would have helped him on his way to fulfil his dream of making Rocawear a $1 billion company.

He added to Women’s Wear Daily magazine: “The goal is to make Rocawear a $1 billion company. It may take us more time than we would like since the economy is in the shape that it’s in, but I’m confident that we will get there. People want a quality product, which is what I want Rocawear to be known for — we make a damn good pair of jeans, that’s why people buy them.”

At the height of the song’s success, fans started taking umbrellas with them to Rihanna’s concerts so they could copy her dance routine. However, the items were eventually banned from shows to stop audience members from injuring themselves.
