The US R&B star, who has worked with the likes of Justin Bieber and Justin Timberlake, was impressed by the British rapper when he joined him on his European tour.

“We talked about doing something together. He expressed an interest. He's a great guy,” Usher told the Metro.

Earlier this month, Tinie Tempah was nominated for four BRIT Awards, which take place in London next month.

The rapper has also denied reports that he is set to perform at Prince William and Kate Middleton's wedding in April.
