Kesha has agreed to officiate a same-sex couple's wedding.

The 'Tik-Tok' hitmaker was at the premiere of her new documentary 'Rainbow: The Film' at the Metrograph in New York on Thursday (09.08.18) when a loved-up pair - who she had previously been posing for pictures with - asked her to marry them.

The sweet exchange was captured on camera and published on TMZ as the unidentified pair said: ''We want you to officiate our wedding.''

To which Kesha replied: ''Well I do that! I do officiate, when are you getting married?''

The girls shot back: ''Whenever you're free!''

The 31-year-old singer giggled and said: ''Well I'm going on tour but yeah I do officiate weddings. That's so sweet. This man and these ladies, they do my schedule. Are you engaged? Congratulations! Thats's so cute!''

Meanwhile, the blonde beauty has been locked in a bitter legal with Dr Luke, who she accused of sexually abusing her, drugging her, and emotionally abusing her for years, and she recently admitted she gained strength from her ''darkest moments''.

She explained: ''It's from our darkest moments that we gain the most strength. There were so many days, months even, when I didn't want to get out of bed. I spent all day wanting to go to sleep, and then when I did fall asleep, I had horrible night terrors where I would physically cry and scream through the dark.

''I was never at peace, night or day. But I dragged myself out of bed and took my emotions to the studio and made art out of them. And I have never been happier with a body of work as I am with this record.

''I hope this song reaches people who are in the midst of struggles, to let them know that no matter how bad it seems now, you can get through it. If you have love and truth on your side, you will never be defeated. Don't give up on yourself.''

Dr Luke has denied all allegations against him.
