Pride in London 2015 started in style, with the news of the US Supreme Court ruling in favour of marriage equality across all 50 states.
Celebrities gathering to honour 12 award winners at the Attitude Pride Awards this evening were excited to welcome the news of legalisation.
Responding to the ruling, Alan Cumming, actor, LGBT activist and host of the Awards, said: "I'm delighted, I couldn't be happier. I think it's great. It's really a great day for America and the whole world."
Bruno Tonioli, Strictly Come Dancing judge, said: "That was a long time coming. Many states have had it legal, but now it has encompassed the nation, which is a wonderful, wonderful thing. Because why not? We're all the same, we should have the same choices."
Harry Potter actor Matthew Lewis said: "I saw it this afternoon and I thought, 'Man, tonight's going to go off now'. I think it's absolutely fantastic, long overdue. It's just a victory for love, I guess."
Singer-songwriter Conor Maynard said: "I think the whole world needs to hurry up. Obviously it is amazing and it is worth celebrating, but it should have happened a long time ago."
Robin Windsor, former professional dancer on Strictly Come Dancing, said: "It's unbelievable that it happened the day before Pride, and it's put everybody in such a great mood and high spirits, ready for such an amazing weekend."
Responding to former Strictly colleague James Jordan's comments objecting to same-sex couples potentially competing on the show within the next few seasons, Windsor said: "I think it would be an absolutely fantastic thing.
"Again, the same as we say for 'same-sex marriage', really it's just 'marriage'. People say 'same-sex dancing', really it should just be 'dancing'. Anybody should be free to dance with whoever they want."
On Monday, Jordan told The Sun that he opposed changes to the show's "traditional" male-female couples: "Ballroom and Latin dancing is about a man dancing with a woman - that's fact."
However, Windsor said: "Ballroom dancing is actually made up of a leader and a follower. It really doesn't matter who does it, where they do it, and who they do it with."
