Queen's Brian May has paid tribute to Lady Gaga, describing the singer as a “phenomenon”.
The guitarist appears on the singer's recent single 'You And I' and performed the track with Lady Gaga at the MTV Video Music Awards in September.
Speaking to Sky News, May said he was a big admirer of Lady Gaga as an all-round performer.
"She is a phenomenon. She is very focused. She's full of ideas. She's one of the few people I have actually seen who can genuinely dance flat out and sing flat out at the same time,” he said.
"I love working with talented people and we don't have Freddie anymore, so it's great to get out there and do things."
May is currently taking part in celebrations to mark 40 years since Queen formed.
