The 'For Your Entertainment' hitmaker recently caught the 'Diamonds' singer's show in Detroit and admits her singing skills blew him away.

Speaking to Laura Whitmore for The Hot Desk, she said: "I like Rihanna's Instagram page because she's so fun to look at. She's so gorgeous. I went to her concert in Detroit a few weeks ago. It was the night before I had a concert there.

"I knew it was going to be a great show anyway because I know the songs, but I was blown away. It was such a good show ... the design and everything was really gorgeous and she delivered some vocals! I was floored ... I was really impressed, actually."

Meanwhile, when it comes to his own music, the 34-year-old singer has been performing with Brian May and Roger Taylor of Queen for the last few years and says it has given him "a great confidence".

He shared: "[It has given me] a great confidence. Public reaction to the group's concerts [have been] wonderful and the tour gave me the opportunity to make myself known to more people."

When asked if he feels differently about performing with a group rather than solo, he added: "I would not speak of different emotions but of different ways to approach the show. With the Queen I have to be really exaggerated, bordering on the ridiculous, even the costumes, because it is the music that requires it, I have to be drawn into the role.

"In my tour instead [I] explore the current fashion and dance and I can express my creativity. I have taken care of every single aspect of the show."
