The 'Skyscraper' hitmaker was among the celebrity presenters at Logo TV's Trailblazers ceremony, which honours those who have championed lesbian, gay, bisexual, and transgender (LGBT) rights.

She took the occasion to share her own experiences with the LGBT community, explaining how her own grandfather had 'come out' in the 1960s, reports contactmusic.com.

She told the crowd: "I've never spoken about this before, but my grandfather was a trailblazer himself. He was brave enough to come out in the 1960s, and I feel that a lot of my spirit has come from him. He passed away a few years later and I only wish he could have been able to see all the progress that has been made.

"It's such an honour to be welcomed and embraced by the LGBT community, so thank you very much."
