The `Suit & Tie` hitmaker is looking to become a landlord of a drinking house while he`s in the capital for the Yahoo! Wireless Festival - where he will be performing two concerts, including one with Jay-Z, at the Queen Elizabeth Olympic Park in July - and the singer is said to have already set his sights on an establishment.
A source told The Sun newspaper: "Justin likes the idea of having his name above the door, he`s looked into buying historic East End boozer The Blind Beggar for a while. But it isn`t likely."
Justin, 32, will also be joining his rapper friend for their `Legends of the Summer stadium tour later this year.
Jay-Z - real name Shawn Carter - has hired a cigar expert to join the pair every step of the way to roll a smoke for guests at each venue.
An insider previously revealed: "Jay met this cigar expert at a friend`s private party recently. He had been hired to roll cigars for guests in a smoking room.
"They were chatting for ages about the origins of tobacco and all the different types and then Jay-Z offered to have him on board for the tour dates."
