Kesha has promised to kiss someone "on the mouth" if they return her missing jacket.

She said in a video posted on Instagram: "If you can get me my f***ing suit, I don't know what I'll do.

"I'll kiss you on the f***ing mouth. But I need it for my show tomorrow.

"If someone can get it, I'll do something great for you but please I need that f***ing suit by tomorrow night at 9 o'clock. OK, I love you. Bye."

She added in the video caption: "if u guys can please help me find this suit jacket. i will be forever indebted. i need it for my show tomorrow night. someone stole it from my room. can anyone help me?(sic)"

During another gig at the weekend, Kesha - who has been through a lengthy legal battle in an unsuccessful bid to get out of her recording contract with Dr. Luke and Sony Music after accusing the producer of abusing her - admitted she couldn't have made it through the tough times without the love of her fans.

Speaking on stage at the Waterfront at Harrah's in Atlantic City, she told the audience: "You guys stuck by me during the hardest f***ing years of my life. I'm serious I could not have made it through without you."

And the 29-year-old singer stressed the importance of "hope and faith" when "stuck" in a bad situation.

Introducing her final track, she said: "I'm sick and tired of hearing I can't sing. This really sums up my life right now. When you're stuck you gotta have hope and you gotta have faith this one's called I shall be released."
